I have gone every year since it’s inception and most years have been really good. My advice is get there early and start on the top floor of the north tower. The elevators are the Achilles heel of the show. Use the stairs to work your way down between floors. This save at least an hour of waiting on the elevators.
Make your plans for each floor floor and visit the rooms you want to. Be careful not to get sucked into some sales pitch in a room where you really have no interest. The hardest part for me is some rooms are so crowded it is hard to get a seat and just as hard to get answers to questions if they are carrying a conversation with another patron. You hate to be rude but you find that some people are naturals.
But the show can be fun and informative. Some rooms will sound exceptional and others may have great equipment but not sound good if they are limited in set up options based on the room. I live in Colo and we have had the hottest summer I can recall in 60 plus years. The problem this creates is they may keep keep the AC off to keep the noise down. Hotel rooms are small and 10-15 people plus equipment can heat a room up beyond comfort. Drink plenty of water, but know where the restrooms are. Most rooms won’t let you use the restrooms in the rooms as they stuffed with equipment boxes.
But you will enjoy the show especially if you have never been before.
i know I plan to go, oh one more note, if the Broncos are playing Sunday it can reduce attendance but some vendors break down early.
Have fun and safe travels
