A private villa would be best for you I think. Especially if you guys are fond of having exclusive party for your selected friends. If you could, try in Bali Island.
I would go to Hawaii, but it all depends on how much money you have and it depends on if you want to drive or fly. I would go on a vacation that is with 8 hours of where you live.
Dubai is very nice place to vacation
I hear Afghanistan is nice this time of year.
