Sleeping bag might be an advantage...space is going to be severely short this year with many guests and the normal number of "goddamned drunks" that cannot depart until cleared.
I have a 6 and 12 string acoustic and a classical as well as 2 electrics. If you want to bring another 6 steel its up to you. We've never spontaneously broken into song...but you never know. Stranger things have absolutely happened.
