What time does their office open, or concierge arrive for the day? I have been trying to call (7-8am EST) to discuss rates but no one has been answering.

I would wait for the a team on Monday and asked for sales. It sounds like you need the a team. Good luck!

It is tricky with being the 4th of July weekend and all. But by 830 a.m someone should be there to help you. Noone from the office will be there but a front desk agent would also know the answer to the questions you may have.

I don't know. Maybe try 10 am.
