Hi Tiffany,
Thank you for stopping by the Disney Parks Moms Panel. I am glad to hear that you are thinking of even the smallest details to make your trip go stress free. Planning ahead for meals and budgeting by eating breakfast in your resort rooms is a great time-saver, as well as money-saver. My family has done this on almost every single trip we take.
I have great news for you. You will be able to purchase half gallons of milk in most of the resort hotel quick service or food court's grab 'n' go sections. I have never personally seen full gallons sold, but half-gallons are a better choice, anyway, due to the space limitations in the mini-fridges in the resort rooms. You will also find individual yogurts at most of them. In terms of cheese, I do remember seeing individual cheese sticks before. However, since this is not something I have looked for and bought on a regular basis, I cannot confirm if there are other cheese choices. You will also find fruit, prepared sandwiches, and other individually bottled drinks. Depending on the item, some may even qualify for snack credits, if you have the
Disney Dining Plan.
Have a magical trip and feel free to stop back with more questions as your trip approaches.
