Bandwidth for a weekend @ Gaylord National Harbor, DC metro area

[telmnstr]

I help with an event at the Gaylord at National Harbor in Maryland. It's a 
music and video gaming festival. The network team for the event is looking 
for options on getting bandwidth for ~5 days across a weekend at the 
hotel. RF or handoff in building.

The large array of clearwire modems isn't cutting it any more.
Looking for pointers I can give them. Please email off-list.

Thanks!
