im having a house welcoming party in october. we are going to move into our new house soon, and we want to have a party to celebrate when the building is done. we may be able to rent out a clubhouse, which has a ballroom, dining hall, an indoor pool, and an arcade for the kids. we may have up to about 50 people, mostly adults, but some teens (12-16 yr olds). what are some ideas for decorations, food, and games? a theme may be nice, but it is not necessary. thanks a lot!
