We had this problem 3 weeks ago. We had one Deluxe Meal Credit (not considered CS or TS) left at the end of the trip, and no time or room for eating! We asked at the confectioners on Main Street if we could exchange it for snacks, and were sent to City Hall. CM there said they can't approve them to exchange it, and it's up to the CM at the sweets shop- that some older crew would approve it and others would not. No one there would do it for us. We debated going to WPC in DTD and getting a meal to go, but didn't want to ride the bus or boat as we were ready to get on the road and go home. We tried at the general store in POR to do the same, and were told only the cafeteria could change credits. There we were allowed to change it to Continental credit- any 3 snack items made on the premesis or bottled drinks. We got 2 bottled juices and a Mickey rice crisp treat. $9.98 worth is not a great value for that type credit, but it was better than nothing. Even with wasting it that way, we still ended up more than $100 ahead with the DXDDP for what we ate in 4 days.
