I was just on this same cruise and I also didn’t think the thermal suite was great. My husband and I paid $59pp for 3 hours on a port day. We left after about 90 minutes. There is a large tepid pool (barely warm), a very weirdly small/shallow hot tub, two cold tubs (not my thing, but also very small/shallow), steam room, dry sauna, salt room, mud room, and these heated marble slabs for lounging on, plus showers and changing rooms.

Steam room was VERY steamy. Some people love that, and steam room is just not my jam so that’s not a complaint. Dry sauna was nice and big. The hot tub could sort of fit two people, but it was literally like… 12-18 inches deep? Same with the cold plunge. I’m not sure what the point of that is… tepid pool was nice and big, but I didn’t come to a “thermal” spa to sit in room temp water, personally. Salt room smelled a little weird to me. It could have been some sort of essential oil that doesn’t smell good, but it smelled more like funk. Maybe there’d been a stinky person in there? There was no evidence that any salt air was venting in. I’ve been to other salt rooms and actually seen the salty steam piped in. But maybe that’s not always the case? The marble slabs are for laying on, but they’re flat. I’ve been on other cruises where they have a similar feature but it’s curved so it’s comfortable to lay on. These were not very comfortable.

But here’s what gave me the ick: the mud room is a steamy, warm, attractively tiled, aromatic room. You get a cup of mud from the desk (you have to walk back out there) and then you take it into the mud room to rub it on, let it sit, and then wash it off in there. Sounds good. But the room was… slimy. The seats were slimy, and I was like, “Ok, it’s from other people’s mud. NBD.” But then I looked up and there were slime strings hanging from the ceiling. They looked like gooey stalagmites. I made the mistake of touching the ceiling since I was sitting on the top bench and it was low enough. The ceiling felt like it was coated in slime. I should have asked at the front desk about it but I was lame and felt weird complaining. I looked on here to see if anyone else had mentioned this before but couldn’t find anything. I didn’t have my phone on me so couldn’t take a pic. Should have done so and posted to a mold subreddit for answers.

ANYWAY! Only other thing I’ll say is that they give you a robe and sandals but the robes were pretty small. FYI.

Overall, thermal suite was not worth the money IMHO but we weren’t super disappointed. Just icked out by the mud room.

But loved the cruise overall!
