Dang! Now I regret not going solo when I had an annual pass. It was tough getting someone to go with, I considered going expressly for Xmas shopping and to just do it for novelty sake. Now that annual passes are prohibitive that opportunity isn't going to come again.
I think if you're open to meeting people- approachable, smiles go a long way- you will meet folks. Also, people often post in here who are either going solo or open to meeting up. Have fun!
