I'm pretty sure I own more than 20 swimsuits...some one-piece, some bikinis with mix and match options. It's easy to pack more than a few swimsuits if most of them are bikinis...they don't take up much room. I wouldn't dream of judging someone based on how many different suits they wear on a cruise...lol. If I want to get sun, I'll go with a suit that has a bandeau top and a cheeky bottom. If I am swimming in an ocean with waves, I want a top with straps and more coverage on the bottom. If I'm doing a combo excursion where I'm in town and on the beach, I might opt for a one piece suit that can sub as a bodysuit as well. I don't do hot tubs but I'll be in the ship pool on sea days for sure. At the end of the day, we all do what we choose to do to enjoy our cruise, right?
