I took my niece to Disney the first part of December, while we were at MVMCP she got one of the $6 helium balloons that were green with Christmas designs on them, no Disney characters. These balloons have and extra plastic layer on them. We tied it to the stroller, made it very easy to find, anyhow that balloon lasted all week, so we took it to the airport with us, didn't think they would let us take it on board, but they did, I have a picture of it on the plane tied to a row of empty seats. I saw my niece last week and that balloon still hasn't deflated! Talk about a bargain!
