We had our daughter's last birthday party at our local library. Freeman Library in Clear Lake has a wonderful children's room that you can use as long as it's not reserved for something. The great thing is, this is free! You provide the food and decorations but you get a huge room to use. Also, the kids loved checking out books after the party was over. My daughter loved it. You could even make it a "donate to the library party" if you want, where every child donates a book in your child's name. Good luck!
