hehehe
1,000,000,000$ should get you a nice party ;)
But okay, fun aside, drinks are around 8 to 15 in most clubs. Cover is between 10 and 40 bucks. Vegas clubs have started to coordinate with each other, so every night of the week has one or two “in” clubs where the party is raging, while the others are mediocre to closed. If you want to hit the good clubs, you should definitely invest in VIP line service, or you’ll spend 2 to 3 hours in line to get in. Line service is about 100 to 200, just google Vegas VIP line service.
Food. If you want to get “edible” food, and want to eat on the strip, you should calculate about 40 per head and meal.
As for the clubs, crowds are raging and alcohol flows freely, so don’t calculate going out and having two drinks, never happens this way, not here anyways. So, I’d prolly calculate 300 to 400 a day at least, unless you wanna do discount Vegas, which sucks.
