You're asking for trouble...
Dude - the only SPs you will find working at 2:30am are the ones from the SUN. They will likely figure you really need some action, and will tell you one thing on the phone, get you there and start charging you for 'extras'. You may also be subject to bait and switch....
Your call - you can book with someone that advertises on the web, with pictures and a profile or take your chances with the SUN.
Good luck - (and don't say we didn't warn you).
