Im not sure how many people Ill have on the floor sleeping
Useless - I think it is worth it to go to the floor once in your life - of course in Vegas (at least at the V) there is a secondary "meeting place" at the round bar in the center of the casino - usually stocked with a large group of crazies and is a good place to find people even if your own parties have closed up at 3 am or so.
It will be interesting to see if AVN plans on continuing the tradition of trying to feed everyone as part of the cost of the floor ticket and as well - tries to make sure no one can get into anything without that ticket. They seemed to be able to control it in Fla - but this being a triple convention with the CES exhibits also at the V this time it will be a tough road for them.
