Not many of us choose the dining plan, so I'm not 100% how it works. Do you have your vouchers with you? Are they still vouchers for dollar amounts, or are they now for meals in general? If they are still the ones for dollar amounts, make sure that to get your money's worth by spending the full amount - they do not give change. I.E. If you use a $5.00 voucher to get a $4.00 pretzel, you will not get your $1.00 back.
I'm curious if they are still the same?
ETA: I went to
Disneyland's Dining Plan website and couldn't find the answer there.
