Swimming vacations for floaters?

I love swimming! When I learned about these organized swim tours, I was so excited about a swimming vacation. However, as I learned more about them, I realized they're geared more towards people who actually swim laps and are interested in going some sort of distance. I'm a confident swimmer, but my idea of a relaxing swim vacation is more jumping off the back of a boat and floating, hot springs dipping, playing in the waves, tanning on a paddle board, chilling on a sandbar, etc. Does anyone know of any tours that cater towards this sort of crowd? I'd love to experience beautiful wild waters, but don't necessarily want to swim any sort of distance in those waters.
