we are having soem pretty significate issues ourselfs.
The best one is the "150$ " electric charge, "cause those speakers use a lot of electricity", .. all 500 watts
add another $250 for the "distro" that you have to find, and plug in yourself.
the one taht takes the cake however, is the "loading dock" charge. 1 dollar/3 lbs, what we loaded though the dock ....
We didn't inquire as to if people counted in the weight total.
I think the way things are going to start happening, is that peopel will do events, and just not tell the hotel that they are bringing in 3rd party. A few of my clients are doign this already.
