Hi all! I'm about to start booking hotel rooms for my guests (i'd say about 90% are out of towners, as we live where my fiance is stationed). We have about 110 guests, which is about 40 families. I've picked the hotels, but I really don't know how this works. I found 2 hotels that I like, and are affordable. Now, do I assume all families will be using what I book, and do 40 rooms in each hotel? That seems like too many. Do I do 20 in each? What's the formula here? Also, when we book, do we put money down, or do the guests do that when they confirm? How many days should i book for? Help!
