Speaking from the view point of Tampa's Readers Weekend, The price that you've stated is fine.
Especially since I know that so much more will be include in this price, not only schmoozing, but meeting and making new friends, dining out without the kids, going to the bathroom without the kids, not having to taxi the kids here and there, and....get my drift. NO KIDS!!!!!LOL
But seriously, I think it's a great price. For those who are thinking about going, airfares now should be pretty good. The closer you get to the event, the more it's going to cost. Duh, right? Book your flight now and consider a roommate for the hotel room.
