On our last trip, we were 2 adults and 1 child on the DDP. The trip was July 1-6, only DH had to leave the afternoon of the 4th to go back to work, so we were creative with our credits.
July 1-dinner was CS credits
July 2-breakfast at CP (everyone use a credit), snacks, Ohana dinner (everyone used a credit)
July 3-breakfast in room, Sci Fi lunch (used 1 adult credit for 2 milkshakes and a burger, plus ordered onion rings and another burger for cash...son and I shared one milkshake and 1 burger), snacks, CS dinner
July 4-breakfast in room, Tusker House brunch (everyone use a credit)...Cape May dinner (only son and I, we both used credits)
July 5-Le Chefs (son and I shared 1 adult credit and I ordered him an orangina), CS dinner
July 6-1900 PF brunch (only son and I we both used credits)
I have to say that at Chefs and Sci Fi, each waitress was very nice about the splitting, and the Sci Fi waitress was great about letting us get both milkshakes at once (even though one counted as the drink and one counted as the dessert). Neither waitress split anything for us, but it was no problem.
