It is a Hilton thing. The charge is for them to supply a 'separate' feed, just let them know that you are OK with the wall power and there should be no extra charges. I did a winter formal this past November at a local Hilton and they charged the school $100 for a power feed. I told the school principal who hired me that we didn't need it but he said, "It's only a hundred dollars." So they'll spend $100 on something they don't need but ***** and wine about a DJ that charges $100 more than the other guy. WTF? Here is a photo of the panel they provided. Notice how the main wire enters the box with no conduit fitting? I didn't even use the box, just one plug on each side of my riser. The outlets were all tagged so I was sure they were on separate circuits. My set-up is very energy efficient, even my Le Maitre hazer only draws 140 watts max.
