Our company (based in LA) has party today at Vegas. A friend of mine decided to take the plane from LA -> Vegas, I took the bus, other people drove their cars.... And somehow I got 30-60 minutes earlier than him, if not more. Granted, due to the rain it was much harder for the planes to take off, but adding checkin time, checkout, taxi to the hotel, etc...
On top of that we had nice 30 minute break with the bus, at not so bad place (In-N-Out). And plenty of room to play monopoly on the iPad, read books, drink wine, stroll around, etc.
