Nick Hotel: Has anone changed ressie due to poor weather?

[riu girl]

Due to stay at the Nick Hotel mid Dec for one night and according to long range forecast the weather looks very poor for that day. I know you can change/cancel a ressie 72 hrs prior to check-in but has anyone had any experience changing a ressie LESS then 72 hours prior to check-in? I
would like to have the opportunity to wait to we get to Orlando and check the weather forecast at that time.

Thank you
