Beaches & Cream is open 11am to 11pm daily. Just a few words of advice:
1) If you go when or very shortly after they open, they have virtually no wait.. if you don't expect to wait (it is VERY small, worth it, but VERY VERY small).
2) From PAINFUL experience,
DO NOT plan to go there shortly before they close (to the take out counter) just to get a last something. When we did it, passing several cast members including at the door itself (to the take out counter) at somewhere been 10:50 & 10:55pm, there was only 1 CM working & he was taking care of two pretty, young girls. After he finished with them, even though we were already inside, had not been stopped by other CMs, & in fact he hadn't said a single word to us when we were clearly there waiting while he took care of (& flirted) with the two girls, he told us that they were closed & we had to leave, without having gotten to order anything!
So, keep those 2 little tips in mind, & you should have a WONDERFUL time!
Enjoy the Magic!
