And they are perfectly fine with the crowd. I've chatted with many hotel staff and almost all of them are happy with the DC crowd. Generally tips well and are polite even when drunk, some assholes, but thats normal with any crowd.
Worst case scenario is usually they tell people to disperse, but otherwise, they always seemed to laugh when they saw shenanigans (except for people fucking with Casino machines, thats a fast way to make them mad)
Probably, because of what mrandish said at the start of the thread. Management thinks they can earn more money from others. If hotel staff is treated well and/or gets good tips doesn't factor in the decision process which event is hosted. As long as someone spends enough for managers to get their bonuses management is happy.
It doesn't appear there are any similar sized conferences scheduled for the original time slot though? Or that there will be one in the near future, unless you know of some information.
