We had my daughter's 2nd b-day party at Jump'N' Jone in McKinney. It is an indoor inflatable bounce house. They have an arcade room and private party room for the cake and presents. It was alot of fun for the kids and parents.
Also since your party is in the fall, have you considered a pumpkin patch party. My sister in law had her daughter's party at The Pumpkin Patch. She sent out invitations she desiged like a pumpkin. She put raftea ribbon on it and made it look really neat. They have hay rides, petty zoo, pumkins to paint. She had hot dogs and drinks provided. They have tables and a covered area. It is located Aubry, TX. It's not too far away. She had a really good turn out for the party and everyone thought it was a really fun party. You could even let the kids wear there Halloween costumes.
