If it is indeed something you're hoping to utilize multiple times (WDW, camping, hiking, etc.), take the time to research and find something that "breathes." Nothing more miserable than putting on a raincoat/poncho in the August Florida heat and sweating underneath it more than you were already sweating without it! I have almost reached the point that it's just easier to carry an extra shirt to change into in case my first one doesn't dry out fairly quickly. Our kids are also getting old enough that if they are begging to get soaked on a ride that isn't floating my boat (see what I did there?), we can just send them on the ride without us...but admittedly, there are few rides that I'm not going to want to ride myself, and they know it!
