Just a word of warning. My DS5 (at the time) used a swim vest at Typhoon Lagoon last fall and woke up the next morning with a rash all over his chest, shoulders and back. We spent the morning at a QuickCare facility near DTD instead of at MK. The doctor gave us a couple of prescriptions that cleared up the rash in a couple of days.
I suppose he had some kind of reaction to the cleaner they use.
