Where in Florida are you headed? If it's Disney World, you're all set. There are restrooms there that are set up like what Brits call Changing Places. Be advised, those aren't called Changing Places, but my mom said they did have big enough tables for adults when she took my family member. Now, do you need the physical space, and equipment to do it yourself, in which case, that would be enough, or, do you need an actual human to help you change? That's harder to find. I know, because I have a family member who could really use the same help she gets from her home health aid, when we go on vacation. Hmm. . . There are a few home care agencies that have travel companion programs, if you do need an actual person.
