I go to Jellyrolls solo all the time. I usually sit on a bar stool in the back of the bar (I always sit in the same spot--if I'm not sitting on my stool, some of the piano players notice). I always go in to the left, and sit on the first bar stool, right next to the steps down to the pit.
I never take a table when I'm by myself--I would feel guilty about taking a table for four by myself, but that's just me.
So go, and have a great time. I highly recommend trying to see Scotty and Ray when you are down there.
Also, LittleMissMickey is down there around the same time as you (although I'm not sure if she's going the same dates). Perhaps she'll respond to this thread and you can meet up--she was trying to find someone to go to Jellyrolls with.
Any other questions, let me know.
