My dh bought 3 of these off of Ebay -- mine is Tinkerbell, his is Mickey Mouse and ds(3, nearly 4 when we go) has Lightening McQueen. I'm not sure if ds will wear his while in the parks, but we thought it was worth a try.....
We figure that we'll all have things that we want to carry but not in our hands -- between park tickets, (play) money for ds (allowance per day he bahaves on trip to buy what he wants during the trip [yes, we bribe]) and, of course, pins for trading.....
Just our thing...no such thing as a wrong answer here.....
