Not as good as at WDW. Plain and simple.
DLR's plan gives you vouchers for $ amounts (not meals or snacks like WDW's) and you can use the vouchers for meals. And when you use them, you don't get change back. ie: If you were to buy a soda for $2.95 and you paid with 3 $1 vouchers, you wouldn't get your .05 back. If you paid with a $5 voucher, you wouldn't get your 2.05 back. Plus these vouchers are not good at DTD, which is where all the good sit down restaurants are (other than Blue Bayou).
