When we were down last week we decided to do this and it worked out so well that I thought I'd share. First off though, we stayed at Pop Century so I only know for sure that they have it there, but I'm assuming they probably have it at any on-site hotel. So...here is my tip. On the back of the lifeguard towers around the pool they have a chalk board that they fill in every day with the weather, hours for difference parks, the date, etc. It is a nice way of keeping a record of what it was like each day.
