well I left out the price of alcohol because I know we have some hard asses on this board

who could drink the entire navy under the table but here is a pretty good break down.
If you drink 10 beers a day - which for most is casual drinking on the beach during the day and maybe one or two when you get to your condo - comes to about 70 --> 3 cases --> about $45
If you get a 2 bottles of hard stuff, girls seem to like the Blue UV --> that will run you about another $35
If you're gonna mix that with red bull, which isn't bad but its gonna be about $2/can so if you have 2 a day that will be about $30
After all this drinking you shouldn't need to spend much more than $20/day at the club. ---> $140 Remember you don't need to be passed out drunk to have a good time, you just want that good buzz, and if you lose that good buzz it only takes a couple drinks to get it back. Obviously this depends on if you're buying shots and high price drinks or beer.
That comes to about $250, obviously a lot of that can go on the credit card, unless you're underage and need someone to buy for you. And then you'll be substituting the $140 with much cheaper alcohol in your room.
Plus, if you get most your food at Wal-Mart or eat cheaply when you go out you won't spend that much on food. I plan on getting a lot of cold cuts and some Tombstone pizza's. I believe I'll find better things to do than waste hours of time sitting at some fancy restaurant.
Also, I'm not gonna go shopping much, except for maybe a hat. So if you plan on doing some shopping you might need to factor that in. The beach stores have pretty cheap swimsuits and they have a much larger selection than stores in the north.
