Most of the resorts at Walt Disney World offer some kind of evening entertainment. I stay at Disney's Pop Century Resort both for the value and because I love the place. My last vacation I was in a premium room in the '60s section, overlooking the Hippy Dippy Pool.
The evening entertainment every night at 9 p.m. is a movie on the pool deck (weather permitting). I noticed a lot of families gather for the movie, I think to give there kids a chance to wind down from a sometimes overstimulating day. You can also watch the movie from the pool, if you are so inclined, like I was!
Here is the view of the pool deck from my 3rd floor room. While the soundtrack from the movie can be quite loud, it is usually over by 10:30 p.m., the pools close at 11 and time to sleep.
