Help! Looking for a 'castle' for baby's 1st bday!

I am looking for a castle for my baby's first bday party. All of the 'real' castles are SOOO expensive. I just need something that LOOKS like a castle. THe only thing I can find was White Castle!!! I don't care if it is a kidsjumping place, a party place, a restaurant, ANYTHING! Please give me suggestions
