If you get up in the morning and hit the convention center when they open the doors, no problem getting your hands on lots of stuff to try. Musicians don't tend to be early risers.
Would've been a good tip, but I was there before 10 all 3 days. I skipped Sunday as it's impossible to actually see anything beyond casual walking and talking... . Mornings are just as crowded. Been there since 2000 every winter. I still have a lot of fun. I don't care how loud it is or it takes 45 minutes to get a $20 hot dog. I enjoy it very much so. I've been able to find job opportunities in the past when I was looking for a job. It's been a very positive personal experience for me over the years.
