First time flare up... Swimming in Disney land????

This year I have had my first real flare up of psoriasis. I'm amazed at how how I never knew how bad psoriasis is or what people put up with. It's now covering face, stomach, elbows, legs, back and (ahem) other places. It's bad enough people staring in the street and my husband has been brilliant but we are going to Disney in a couple of months and I'm terrified that people are going to look at me like I'm diseased, worse still what if I get asked to leave ?! How do you deal with this? I'm not going to let it stop me have fun.
