Hi,
I have twin girls and we also have a lot of friends with kids, so we opted to have their first birthday at Brookfield Zoo. There birthday is in June, but they also have an indoor room to have the party. If you choose, they can have games to play for the older ones also. They did a GREAT job and my husband & I highly recommend having a party there. They take care of everything right down to the treat bags.
Good luck & congratulations.
