I can't believe any of this advice.
You should have gone for the new tried and true American method. You should have complained about the party but stayed in the room. At the swim meet, you then should have had your daughter pretend to drown, but get revived by the lifeguard. At this point, you can sue the hotel for not providing a safe enviornment for your daughter and claim she almost drowned due to the lack of sleep cause by the loud party below your room.
Jeesh, don't you people know anything.
