I tried searching the forums but couldn't find any matches... so please don't hurt me

One of my concerns is that some of the hotels I've emailed for proposals are telling me the music off curfew is on average about 11pm. Are you all ending your party by 11pm? My people love to party I think 11pm the party would just be getting good!
Any ideas on how to deal with? Know of any venues where the music/noise off curfew is after 11pm?
Thanks!
