Hey Fu,
The best place for college kids is probably Ballys Wild West Casino. CHeck them out first and they usually always have at least a 15 min table no matter what time you go.
Park in the bally's garage and its actually closer to the Wild West Casino than doing vallet. Plus its cheeper (2 bucks). However when its packed (like on holidays) it can get full. Thats when you need to do vallet.
When you go to Bally's Wild West make sure you sign up for the MVP card as they ALWAYS give you a free Room Comp and some free money for coming back. You will also get a free comp without even playing much if you ask for one to like Pickles restaraunt.
I used to be a regular (every 2 or 3 months) to Bally's Wild West but then I decided I wanted to enjoy other things in AC besides just going there to gamble.
If you like to go to a club..try out the Casbah sp? (at the Taj Mahal).
Another suggestion for a college student is to keep 20 bucks in your car at all times in case you go broke so that you can get home!
