It's one of the best "pure audio" shows around, in a great city at a very pleasant time of the year. It's expanded to two hotels now and seems to really be moving ahead of the competition.
Look at the vendor list and decide if the people you want to see will be there, either representing themselves or with one of their retailers. There's not as much point to go if you can't see the things you're considering for your own system.
Remember, Expedia and Travelocity will NOT shows the fares of the two discount airlines with lots of flights into Denver, Frontier and Southwest. You need to look direct at their sites to get the best fares.
