if you book southwest during the weekdays, you might get a girl on the airplane

then your trip will be a lot more enjoyable.
from my experience, just book directly from jetblue or southwest website...they're pretty cheap. and i recommend to stay at suncoast and rent a car when you get there. i love suncoast because the odds are good, the casino is more loose on the comps and the hotel room are really nice and cheap. i remmeber i paid 80 dollar a night and it was a huge room with a wall to floor window overlook the golf course. very nice. and it is close to the shopping district (for locals), where all the nice resturant and shops are. it is one of my favorate place to stay when i visit vegas during the nfl season.
but now i have gold membership at star alliance, i tend to fly united because i get free upgrades.
have fun in vegas, but avoid the strip...especially bally/ paris paris...those two casinos are filled with assholes.
