Love going to disneyland as much as possible with my daughter, husband - or anyone that wants to go! My husband is a CM and loves working at such a fun place. We have been ap's since our daughter was born.
My husband does security at disney and says that while strollers are stollen fairly regularly, he also has mentioned people often take the wrong one by mistake, then end up leaving it somewhere else, etc. I agree to try and tie something to it to make it easy to identify. Stinks though to have everything taken.
We did it a couple of weeks ago but went with the tutu and t-shirt package (daughter gets itchy in the dresses). It was cute, she had fun, etc. I don't know if she would be interested in doing it again only because she has crazy curly hair and it hurt her a bit.
