We haven't used traveler's checks in many years. We paid for our upcoming Disneyworld trip on-line with credit card, and later added the dining plan so we probably won't actually be spending much more money on our trip.

We may want a drink from the bar occasionally, or at dinner, and I know I'll want a few small souvenirs but that'll probably be about it and we'll just use our credit card for them. We'll have some cash along with us "just in case" (maybe a couple hundred dollars each) but will probably end up bringing that home as we do quite often on vacations. I would hate to be without any cash at all, but we rarely use it and just prefer to use the credit card.
