Yes, I have a smaller house and I always end up with a crowd for birthday parties. As long as you have good eats and fun stuff to do everyone should have a great time! What I always found helps as a nice time filler is to have a station with paper, crayons and stickers or crayons, stickers and paper bags to decorate. (We usually have everyone decorate their own favor bag.) If anyone finishes and activity too soon they seem to gravitate towards the craft table and it keeps them from getting too crazy!
