You can do the highlights of
Annapolis boat show in a day, but not much time for chatting or painkillers. I found paying the extra for the Friday preview day was well worth it. Same displays, but the sales people are fresher and willing to talk. Also, the crowds are about 2/3 of the size as the weekend.
We found that a little advanced planning and honest conversations about what to see saved a bunch of time. Are you really
shopping for a boat, a new piece of
electronics, want to walk on that new Gunboat that everyone is talking about, etc. ? We bypassed whole areas of the show because we did not have an interest in custom mattresses or a new head!
