First, congratulations on your upcoming wedding! We had 110 people with a DJ. We had 2 10-top tables in the smaller alcove-ish part of the room (we had some 12 tops in the main area so they took up more space). I would think you would probably wind up with 5 10-tops in that area. 150 is the max for the room IMO and with a 7 piece band that would be a little tight.
Before you panic, however, do remember that although you are inviting 150 that doesn't mean that EVERYONE will say yes. You may wind up with 120 yes's which would be a much better size. In the end, a crowded room at a wedding is a good thing and there are plenty of places for people to mingle in the alcott!
We invited 150 and wound up with 110. I believe most people will tell you that about 10-20% of your list will say no. No one has a 100% yes rate - espeically if this is not a local wedding (my hometown was in North Jersey). So that should make you feel better!
Did either of you have issues with the seating charts and tables being set correctly. I had read a review that mentioned an issue with this. My fiance's parents are divorced so tables must be in the correct places. Do you have any advice for your you ensured they set the tables correctly.
