FYI Ramadan is not quite a non-issue for those visiting DXB then (I know the OP is not going in Ramadan). Yes you will be able to eat somewhere all day in a hotel - but not in restaurants out on the streets. There is no live music (& that includes DJs) anywhere in the month. Every hotel has to nominate only one bar to be opened and only after Iftar (usually open around 7 pm). Any other clubs/bars have to remain closed throughout. All quite manageable - especially compared to Qatar and Bahrain which go totally dry - but not quite "business-as-usual"
