Hi everyone! I am booking our WDW vacation today and have a few questions... - If we book with free dining, can you pay to upgrade to deluxe dining? When I try to select that option online it looks like it's making the price go up more than that difference should be... -When is the last time you can use your meal credits? For instance, can we use the meal credits through the end of the day on the day we checkout? -How early can we check into our resort to get our park tickets, or do they get mailed to you before you check in? -If DH and I already have park tix, can our DD use her park tix and one of ours, too? Thanks so much!
