There are 40 venues so unless you stay there for 3 weeks you can't possible visit them all. Even then I wonder if you could!

The main ones for Venetian Trade Beads are:

GIGM Grant Inn, runs 30 Jan - 11 Feb
African Art Village, runs 31 Jan - 15 Feb
G&LW Gem Mall, runs 31 Jan - 13 Feb

Note that Gem Mall is a wholesale show so you have to register as a wholesale buyer with a re-sale license, and I strongly urge you to do this ahead of time since the registration lines are long. If you don't have any way to get in under your own license, maybe some forum member can get you in on a guest pass.

Other shows that have a few Venetian beads to be seen here & there, and otherwise are interesting shows I'd recommend:

Howard Johnson
Pueblo
Rapa River
To Bead True Blue

And, for the first time the Holidome is starting on Jan. 31, just adjacent to Gem Mall, so I'm planning to check it out also.

Check out GemShowCentral.com for more details such as links to the show web pages, shuttle schedules, etc. Plan to be walking 2-4 miles per day, bring a hat & sun protection for days and a warm jacket/sweater for the cool nights, and join the fun!
