You sound like the type that would enjoy themselves on Monday night. Spend a bit of time going back and forth from Crazy Canuk's to Road Kill bar. No joke. On Monday nights, Crazy Canuk's beach bar has Belizean punta band playing and Road Kill bar, a roadside bar across the street, has an ex-pat local band playing. You can get stinking drunk, I'm sure. Been there, done that, took a cab or staggered. I've not tried driving a golf cart in that condition, but I've known others . . .
What you will want to do before you set out for an evening, is make sure the headlights work on your cart and that your battery is fully charged (or gas topped up). I've been out after dark only to find that my cart lights were non-operational. Makes for an interesting trip in the less lighted areas.
