Planet Hollywood is cool, cheapest but still decent spots are Excalibur, Harrahs, Ballys. tip the frontdesk guy $20 and ask for a complimentary upgrade, usually works out pretty well from what I hear.
also try vrbo.com, they have good deals at the jockey club and mgm signature suites for cheap. Try not to pay standard rates for hotels in Vegas, probably the biggest waste of your money, you want to spend on clubs, drinks and stripclubs. Do one fancy meal for the bachelor and keep it buffets/food court/dennys the rest of the way.
Spearmint is the best, and well worth the money spent. But be discriminating, if a chick walks up and first thing out of her mouth is lets go to back room, tell her to kick rocks.
There's way too many chicks in there to settle and if you're a good looking black dude there will definitely be a fine sister or two who's willing to kick it with you a while w/o stressing the champagne room and even give you a dance or two for free.
Also Spearmint will send a limo for you (I think all the main strip clubs do as well) and won't have to pay cover (just call them up) and tip the driver when you get there. If you cab it you have to drop $30 a head. They also have bottle specials from I believe 4-7. (something like $100 a bottle call them for details)
For something like this craigslist is probably you're best bet. Try and find some unlv chicks who haven't graduated full-time to the strip club yet
, good value that way. Don't call any of the places from the people passing out "escort" cards on the street. You will be dissapointed and possibly robbed.
Vegas is definitely worth it, I've drained my bank account a few times after a Vegas trip and have never regretted it. Sitting in the airport broke is a bad feeling, but only cause you're leaving.
Like I said try and save on hotels, do a lot of research and get the best deal you can, esp if you want to stay in a nicer property. That's your best bet for a deal.
Do a liquor store run when you first get there (don't forget water). At the pool parties a daybed/table is pretty much a necessity, you can get away without one in the clubs (thats where pre-gaming comes into play). Also use the contacts on jackcolton.com browse the message boards to see who the best hosts are. hit them even if you're not doing tables, they're usually good at walking you in most spots for a $100 handshake. Nothing like walking up to a packed spot with you crew, giving a head nod and dap to some guy out front, and walk straight in.
Especially if you got chicks w/you.
Make a rough budget before hand and once you touch down try not to think about it.
