The deadline for reserving rooms under our group rate at the downtown Hilton has passed. However, if there’s anybody who missed the window, apparently they are doing a January sale price right now that’s almost as good as the group rate was. So if you still need a hotel, you might look into that.
Alternatively, some people are getting hotel rooms elsewhere. You don’t have to be downtown if you don’t want to be. (Outside of downtown will probably be cheaper, in fact.) However, downtown will be within walking distance of the wedding itself, which was why we picked a hotel there.
