Hi, Melinda!
"Please pardon our dust while we enhance this area for your future enjoyment!"
Yep, unfortunately you will see plenty of these signs around the parks and resorts with construction. I do not know your travel dates, but in March and April you will see construction, especially at Disney's Hollywood Studios as they begin work on major park enhancements. You will also see work being done at Animal Kingdom as final touches are put on the Rivers of Light show and construction continues on the Avitar themed land.
If you want to see specific attractions that might be closed, web-search "Disney World Refurbs" and several sites will be available to show you by month the predicted refurbishment schedules. WDWmagic.com has a great calendar that is easy to read and find your dates. Remember that all schedules are tentative, and attractions could close at any time.
You might also want to keep up the
Disney Parks Blog with all the latest and greatest news from around Walt Disney World.
Wishing you a great Spring Break trip to Walt Disney World!
Cathy
