At the Walt Disney World Resort Orlando, refurbishments and updating rides etc. is high on the list for giving guests the best enjoyment in the Theme Parks, sometimes it can be a little frustrating if you find your favourite ride temporarily closed. Plan ahead for your vacation and you can check in advance for scheduled refurbishments. One web site I found that gives this information and has an easy to follow lay out, is http://www.wdwmagic.com/refurbishments.htm
I hope this helps to make your stay in the Orlando area a happy one.
