Oh yeah, one other thing. Disney Dollars can be traded in for a gift card, but you can't take several gift cards and turn them into one.
My family bought dollars and cards for our kids at Christmas. We wanted for each kid to just have 1 card to take. ( instead of an envelope with multipul dollars and multipul cards).
When we went to the store to trade them into one card each, we discovered that you can't roll them all into one card.
After pleading our case, and stading there with $500 of cards and dollars, the cast member did it anyhow. He said " It wouldn't be Disney if I sent you out of this store today with all of those envelopes."
I thought that was great, and it worked wonderfully for the kids to each have their own card, it make it so easy to keep track of how much was spent.
