There was a big discussion about all the methods of paying for your holiday a while ago, and a few others along with myself use travellers checks. They do accept them all over the park, and in restaurants. Even the front desk at HoJo's cashed them for us every day, we had mostly 100's For us it's the cheapest way of converting Canadian dollars, cheaper than buying cash and a LOT cheaper than using a credit card. I never once had a problem using one, although I did not try at the little carts that sell drinks or popcorn, etc.
