Hi Elyse...
I just had a bday party for my daughter at good old Mickey D's! McDonalds offers a happy meal, cake, ice cream, a goody bag and invitations (if needed). All this for only $7.50 per kid! We kept the whole party under $100 (10 kids)!!! I added a few girly decorations for my daughter, but it really wasn't needed. Did I mention they give balloons for each kid too?
She and her friends had a blast!
