If the casinos want to bring in people badly enough, they can form partnerships with airlines and subsidize tickets. The airline can offer a PHL-LAS roundtrip for $250 as long as the MGM Mirage corporation is footing the other $200.....
I think the "ungenerous" comps are loosening up a bit. I'm going to the new Palazzo (part of the Venetian complex) in a few weeks for a combination bachelor/bachelorette party. 16 people. 4 of the rooms are comp'd and the others are $179 on the weekend nights. The "Player Development Representative" (i.e. Casino Host) arranged the rooms all on the same floor with strip views and some connecting.
The 4 comp'd rooms are the result of minimal play a few months ago by a couple of the guys in the party along the lines of $50 blackjack tables for not more than a total of a few hours in a span of a few days.
I don't mean to digress, but Vegas will find ways to bring people out there. It's Disney World for adults. They (we) always can justify a reason to go.....no matter what the airline.
Oh...and I'm *NOT* flying US from PHL to get there.....
