Anyway, if the OP is not tired and a good nights sleep in a hotel room is not the first priority, it is amazing how much is going on at night time in a city that never sleeps. Obviously, sightseing will not be possible at night, but some restaurants will be open, and hitting the bars in Sukhumvit or Silom is an option. Massage should be possible too (although the OP needs to be more careful what kind of massage place he/she is being lured into)
