We were in the Sierra Tower, room 2562 which is on the 7th floor with a pool view. We were right next to the elevator (we never heard the elevator, interestingly enough) and I think our room was smaller because of it. When we were leaving the hotel and housekeeping was cleaning some rooms, we'd glance inside and you could tell they were bigger, most had sofas, ours did not. Ours had 1 queen bed, 1 nightstand, desk and table with chair. Come to think of it, the one queen bed was wierd, usually its 2 queens or 1 king right (?).
No, we didn't complain, maybe because we were only there 3 nights and one of those nights we got back right around midnight, so it was ending. It is noticeable though, my husband sleeps like a rock and it even woke him up. It was more of an annoyance and we really wondered how a family with little kids that would go to bed early would do. I'm really surprised they would put a band right there at those hours and also, why do they need a band when there is so much going on at Downtown Disney right next door.
