I have never seen The Carousel of Progress and The Timekeeper. I would like to see both on my next trip. Both are listed in guidebooks as "Open Seasonally". What exactly does that mean? Does that mean only really busy days? What is considered really busy? I will be in WDW April 15-23 and am wondering if they will be open then. Are the days open listed on any site that you know? I could not find anything on the WDW official site. Thank you!
