Actually, there is also
http://www.cybernetexpo.com that runs in June. Fay runs a pretty good show, and the last one was (according to all that attended) a very good deal. I am 50/50 on going, the timing isn't very good for me again this year.
As for florida in summer, well... it is when the hotel is both the cheapest and the most available for a full house takeover. Nothing worse than a porn convention filled with "civilians". The Florida show is MUCH more "open minded" than the vegas show. I get the impression they are going to do this show in a different manner, with the whole hotel being turned into one large show, badge required to be part of the festivities at any level. This will take care of the mooches who have been staying in south beach and then just hanging around the hotel lobby to meet people.
The other part of a full house takeover that is nice is that you can be pretty sure everyone you want to see is in one place. Vegas this year was a major waste, considering people were all over the place.
AVN needs to figure out how to lower the hotel costs in vegas to make staying at the show hotel a 100% sure thing.
