Unfortunately for me, I am allergic to the sanitizers in the whirlpools on cruise ships so I can only go in occasionally.  I breakout in an itchy rash that is not fun.  Luckily, our condo whirlpool does not bother me.  So, I rarely use them when on ships but my husband does on every cruise.   I was wondering how many of you do or do not use them when cruising and why?
