I'm assuming your going to just make the deposit to hold all the rooms you want, if so what's supposed to happen is when your guest call to get the rooms and give their info and pay she credits that to your room. If your stay is going to be less than $5000 then she should be crediting you with a check or what you will need to pay when you get there for the dj/band, flowers, decor ect. What I did was made a deposit on only 5 rooms for immediate family and everyone else I gave a date when they needed to at least make there deposit by. If he price is not going to change I would have them make their own deposits. I only did the 5 rooms because I wanted to get the grand opening rate.
