Booked an inside guarantee cabin and got a Promenade Room directly over the small area for designated for entertainment (bands and other musical groups).
We thought we were lucky to have a room overlooking the Royal Promenade, but soon learned we weren't so lucky afterall.
First night into the cruise the entertainment featured in the promenade was the country western band...ended around 10:45 - 11:00PM.
Avoid promenade rooms (w/balcony) overlooking Cafe Promenade. Even cabins located farther aft near Boleros would likely be subject to the pounding base drum and bass guitar.
