We're probably going to go with something very simple. Either ear hats will be the favors at the reception, or we'll do Mickey Mouse rice krispy treats. (Or, as Disney calls them, "rice cereal treats.")
When is your wedding? I like the idea of ornaments--there are some great deals right now-I bought a ton of cute ones, on clearance at Target, that are Micky & Mini themed.
We had a December wedding so did ornaments from Personalizationmall and CDs of the music from our reception. Each couple got one of each (he got the CD, she got the ornament), singles got both. I packaged them with Hershey Kisses with stickers that had our wedding date.
www.fairytaleweddingstore.com has Disney friends sweet tarts. You can put them into little favor holders (organza bags or whatever you choose). They are really cute.
