hi!
The pavillion room has a max occupancy of 100, I believe, but they don't recommend that because some of your guests will be seated in the hallway area (not in the circular area). FTW recommends you have no more than 80 people for a Pavillion room reception. That INCLUDES the wedding party. We loved the Pavillion room, but had too many guests to fit there.
As for the minimum, I believe it is $100/person for 100 people, but if you have more or less people, as long as you spend the $10,000 in food/beverage, you are ok. For example, if you had 50 people and your food cost was $200/person. Keep in mind that there are other fees as well, so your reception will cost more than 10K. Someone else here will probably be able to help you with that.
HTH!
