Hey McLovin,
In Feb when you are down it is a busy time for the island so there is always something happening. Lime, Pedro's, Fido's, Playa, Crazy Canuks, Roadkill, BC's are all good bars each night it is someone hot night for example Kareokee at Roadkill on wednesdays then head down to Lady's night at Wet Willy's. The thing is where you are gonna be is where the party will be as you are a large group and tourists tend to go to where there is a lot of people.
Enjoy and see you in a couple of months
