any tips on meeting other expats to hang out with? (Accra)

Hi folks,

I'm starting work on a United Nations project in Accra, and am traveling to Accra from Vienna on 6th February for an initial 2-week scouting trip.

... need to get a feel for life in Accra (info for a possible relocation decision), and don't really want to spend all my time with work colleagues while I'm there.

... would appreciate any tips on meeting other expats, and maybe going to some parties/get-togethers :)) ?

cheers!

Shahid.
