Hi Dorothy,
Thanks for visiting the Disney Parks Moms Panel with your vacation planning question!
Great thinking! Ordering cases of water, some breakfast foods, and snacks to have in your
Disney Resort Hotel room is a great way to save on the dining portion of your vacation budget. In fact, my family does this on nearly every Walt Disney World Resort vacation. I recommend that you use GardenGrocer.com for your grocery needs. Their prices are reasonable and they are very reliable. When checking out, you will select the date and preferred time for your delivery (within a 4-hour time window). They generally deliver 7-days a week, between 8:00 a.m. and 9:00 p.m. A plus to this service is that if you are out enjoying your vacation when your delivery arrives, Disney's Bell Services will store your order for you. They will keep the dairy and frozen products cold until you arrive back at the resort. Once you get back to your room, simply dial down to Bell Services and ask them to bring your order to your room.
A tip for you: If you choose to bring water bottles into the park (which will save you a fair share of money over the course of a week), you can ask the Cast Members at Disney's many Quick Service dining locations for a cup with ice to chill your water. That Florida sun can warm up a water bottle pretty fast.
Wishing you magical memories,
Kaylene
