I liked going to Vegas this summer, but getting around the strip kind of sucks. Public transportation and cabs are fairly expensive, and the foot traffic is crazy. It seems like it takes half an hour to walk three city blocks (well, everything is huge there). The other annoyance is that people seem to _constantly_ be hitting you up for stuff (sign up for this tour, come see this timeshare development, get a hooker, buy this souvenir, etc). I heard you can rent a car for under 20 bucks a day, but I can't imagine trying to drive around in that traffic, and then trying to find a parking spot.
One trick I learned (well, a lot of people probably know it) is that you can sit at the bar in a lot of the casinos, put maybe five dollars in the machine, and sit there for a long time and get free drinks, as long as you're still technically playing the machine. Nice way to get buzzed for cheap.
Oh, I like the fact that you can have an open intoxicant on the street,too. I also ate at Jimmy Buffet's Margaritaville and got two free margaritas just for buying one, but I think the bartender liked us.
