I tried to spend as little as possible on Carnival's newest cruise ship. I recommend shelling out for better food and more fun.

Josh Weinstein, president and CEO of Carnival Corp, the cruise line's parent company, told investors in late June that the company wants to continue to be known as a "cost leader" in the industry.

Its new ship is a great example of this. Carnival says it's seeing strong demand from its US market. But instead of building a new vessel, the company acquired Firenze and its sister ship from Costa Cruises, another Carnival Corp brand, in 2022.

I went on Carnival Firenze for work, which meant I had to cave on the ship's premium WiFi at $85 for all four nights.

Internet connectivity, specialty dining, and drinks packages are always extra on mass market ships. But over the last few years, cruise giants have added more irresistible pay-to-play amenities to their vessels, all while still luring travelers in with affordable base fares.

On Norwegian's newer ships, for example, this means paying $10 for a round of mini-golf or $29 for an hour at the VR arcade.

Not bad compared to Royal Caribbean's new Icon of the Seas, where travelers have to pay $200 for the fanciest restaurant or $49 for a ropes course that could be completed in less than a minute.

The mini-golf course wasn't nearly as flashy as Norwegian's. But mini-golf is mini-golf, no matter the number of bright lights and animated courses.

The same was true for Firenze's ropes course. While it didn't have the same thrilling floor drop as Icon of the Seas', the multi-part walkway was longer, more diverse, and, more importantly, free.

I much preferred it to the one on Icon.

The arcade was one of the few activities that wasn't free. Then again, they rarely are.

But don't book Firenze if you're seeking a quiet, relaxing ship. I struggled to find a peaceful public space where I could churn out some work without being distracted by the loud music and guests.

The only truly quiet space could've been the spa. But again, I wasn't going to pay for a massage.

Just know that the latter isn't a must-do. Some singers in the cheesy song-and-dance production "Dear Future Husband" were painfully off-key.

And if you want to munch on a bag of popcorn during the movie, you'll have to pay $4. Smelling the buttery snack without having one in my hands was a torturous tease.

Moda Bar and Lounge also had singers, if you count karaoke night.

But if you want a drink to accompany the entertainment, you'll have to spend about $13 for cocktails and $9 for beers and seltzers.

So, late-night foosball it was — for four nights in a row. At least it was free.

But that doesn't exempt Carnival Firenze from the industry-wide push for more pay-to-play amenities. There's a reason the company saw a spike in onboard spending in the second quarter of 2024 compared to the same time last year — despite rising ticket prices.

I doubt it's solely because of increased participation at Firenze's live "Deal or No Deal" game show, which starts at $25 to play. Or the $4 shuttle from the port at Ensenada, Mexico on day three to downtown (which I regret not paying for).

Norwegian and Royal Caribbean's newer ships had complimentary dining that was as good as, if not better, than the premium options. I still crave Norwegian Prima's free food hall.

I can't say the same for my no-fee dining experience on Firenze.

The cruiseliner has a kitschy Italian theme, as its name might suggest. But if I had wanted to continue the Italian tune with some shrimp scampi and burrata at the Il Viaggio restaurant, I would've had to drop more than $40.

So, instead, I had my nightly meals in the mediocre main dining room, which served the same dinner dishes as the buffet.

None of my Carnival Firenze dinners were stellar, and finding a piece of plastic in my pasta didn't help, either.

But continuing my ritual on Firenze would've meant coughing up $5 per glass. It was tempting, especially as the main dining room server stopped by every table with a tray of the colorful concoctions.

My no-spend requirement meant I had to snub the almost $40 teppanyaki lunch, $1.50-a-piece empanada, and $6 Korean barbecue steak pizza (the pizza stand had free and upcharged pies).

That meant none of my lunches were standouts. The burgers were too heavy (mine came with a slab of fried mozzarella), the salsa verde at the sandwich stand was inedible, and the buffet was forgettable.

Even worse, the chicken wings at the buffet cost extra. Oh, Carnival.

It was the only light and fresh meal I had on the ship. I couldn't understand why it and another salad stand were closed until the last day of the cruise.

But a quick pick-me-up at the coffee shop would have required me to break my no-spend rule, too.

The buffet had free coffee, Lipton, and Bigelow's green tea bags. But if you want something closer to your neighborhood coffee shop, the onboard café charges $4.50 for a latte and $4 for a doughnut.

I don't remember the last time I drank that much Lipton tea.

Tea bags at the program were $1.50, unbeknownst to me until I was seated. After expressing disinterest in paying, I was later offered the buffet's teas.

Like any mass-market cruise ship, the most affordable option was a windowless interior stateroom and letting Carnival assign me my cabin.

Traveling alone for work meant I had to eat the solo supplement. My interior cabin, booked fairly last minute, cost $735, including $64 in optional gratuities.

But in 2024, the cheapest itinerary starts shy of $360 per person, including taxes and fees, for the same four-night sailing — from Long Beach, California, to Catalina Island and Ensenada, Mexico — as the one I went on.

This meant the shower — a curtain surrounding floor drains — was one of the largest I've had at sea. And all the furniture came pushed against the wall, making the cabin feel spacious for someone without physical disabilities.

But where the stateroom excels in size, it fails in design.

It was one of the ugliest rooms I've ever stayed in. The furniture looked dated, the bathroom had almost no storage, and there were no bedside outlets.

That said, the starting price of $90 a day is hard to beat. At least it encouraged me to spend more time around the ship than inside my windowless dungeon.

The surplus of complimentary onboard activities rivaled that of more expensive ships. But if my meals weren't lackluster, they were bad.

I'm sure I would have a different review if I had spent an additional $50 on the steakhouse or $100 on the chef's table. But the less-than-desirable complimentary food ultimately plagued my four nights at sea.

If you're considering cruising on Carnival Firenze, I'd recommend paying for at least one of the specialty restaurants. The money will be worth skipping the buffet and uninspiring dining room.
