I'm local so no hotel room for me, but I'll definitely be packing my Hearos or similar this year. I know it's mostly just us old fogeys that seem to care about hearing damage/loss, but seriously, anyone who spends a whole day in that room would be doing at least some (even if miniscule) damage to his/her hearing.
I also mentioned in another thread that I'd like to see them get some "rental power" to help with the 110V load. Many machines were turned off last year and a number of them had signs explaining that it was because of voltage issues. A quick search suggests that a 40Kw unit could be had for the weekend at a very reasonable price, and I'm sure someone could work out the logistics.
Other than that, I had a great time this year and can't wait for 2016!
