I think it depends what you're looking to do and how old your child is. For instance, there is a store in Easton Towne Center called Libby Lou's - they throw birthday parties with rock star makeovers. If you're looking for something at home, google "Hannah Montana Birthday Parties" and you'll get party sites with blogs and ideas on what to do. You could probably do without the actual Hannah Montana plates, etc. and do a nice theme party at home. For instance, have a HM freeze dance, then a karaoke time (you can get CDs with the karaoke versions of her songs). You could also do a craft where they design their own rock star poster. Consider having a "red carpet" when the guest arrive and photograph each little star with sunglasses and a boa. Have fun with it!
