I just read this in the local news and thought I'd share...I don't have any other details...Earl??? 
Rainchecks Available at Universal Orlando
Universal Orlando is now the first of Orlando's big three theme parks to give rainchecks. Originally, Universal officials said the idea wasn't feasible in central Florida, since it rains almost every afternoon in the summertime. However, the torrential downpours of the last couple of months caused a change of heart, so now Universal offers a raincheck that is good after 4 p.m. and must be used within three days. Walt Disney World doesn't give rainchecks and SeaWorld Orlando gives guests second-day tickets good for admission within seven days.

However, I have sent an E-mail asking where they will honor it now. I believe they only do that in the water parks-Not the regular parks, and it is only id they actually CLOSE the park for more than half an hour.-But, it was a "raincheck", so to speak.
