I'm planning to be in Tucson starting on Jan. 27 - opening day for Gem Mall.
My usual stops are Gem Mall*, African Village, Pueblo, JOGS*, the shows at Casino del Sol, and a side trip to Green Valley (about 30 minutes away) to see Venetian beads at the Glory of Beads. The * venues require a resale license and recommend pre-registration.
If you are planning to go - this is a good time to get the cheapest and closest-in room reservations - I use airbnb.
Hope to see you there!
