Okay, I've been slammed since the first day of DEMA so my head is in a hate-the-world mindset right now, so I apologize if I'm not able to restrain that well.
Perhaps it's all the time I've spent in Mexico cave diving, but I absolutely hate loud music for no purpose other than "excitement" and I doubly hate people bugging me to buy their crap. You (or someone from your booth) was awesome when I came by, I was thinking you were going to be one of the annoying salespeople (like the solar charger and massage idiots), but you actually wanted to show me the booth across the way's housings because they had stepped out for a moment. I appreciate that. I appreciate booths that when I walk up, they offer to answer my questions. I do not like booths where the reps just force a brochure into my hand as I walk by.
For me, I'm on the show floor for business. When I see a crowd forming due to free drinks/food or entertainment, I make a note to come back later when it's less crowded.
For me, if I want a party, I go to one of the many parties after the show is over since the work day is done. I kid, I still have hours of work to do back in my hotel room, but that can wait until the wee hours of the morning.
For me, the best way DEMA could improve the show floor is by not allowing those idiot a$$hole solar charger and massage salespeople every block or two, preferably not at all.
For me, the best way DEMA could improve the show is (as I already mentioned) by having decent seminars. I honestly don't mean this to be arrogant, but it's doubtful they could put on a seminar that teaches me anything about online marketing, but I believe in the whole rising tide lifts all ships concept and I'd like to see other people learn something valuable. The other thing would be not to have it in Vegas and if it's going to be in Vegas, go to the fun part of Vegas. The Westgate neighborhood sucks, sorry.
As it all stands, for me DEMA is what you make out of it. I learn something each time (don't waste time on DEMA sponsored seminars and make sure I have a buyer badge since no one cares about the free publicity behind a media badge), they all get progressively better because networking gets better every time you're around the same people. In my position, I'm finally starting to see a change within many of the manufacturers (maybe destinations will get on board too some day) to actually embrace marketing partnerships, so that's exciting for me.
And finally, here's my thoughts on trying to give ideas to DEMA: as Wookie has already made clear, they just don't care. Phrase it as "what can WE do to make it better" all you want, but hoping that this feedback will have any actual change from the DEMA side of things is about as likely as growing gills. I don't say that because I'm negative or pessimistic, far from it, I say it based on years of observation.
