Hiya Kara!
Lovely seeing you here again at planDisney! I was just discussing with my husband today how we needed to plan our grocery delivery for our upcoming trip to Walt Disney World! Snacks are crucial for preventing breakdowns and keeping everyone energized for the day ahead. I love buying quick breakfast items such as croissants, clementines, and individual cereal bowls with shelf-stable milk so that we can start our day and head to the Parks bright and early.
There are quite a few grocery delivery services in the area that you can use. I have not used all of them but the ones I did find below are pretty popular. I have had success with Amazon Fresh, Garden Grocer, and Instacart but I suggest you see what each company has in stock and how the prices fare.
Amazon Fresh
Garden Grocer
Dizzy Dolphin Delivery
Walmart+
Vacation Grocery Delivery
Instacart
Groceries are received by the Cast Members in
Bell Services who at most
Walt Disney World Resort Hotels can even refrigerate any items that need it. You have the choice to pick it up from them or have it delivered to your room at a nominal cost. Make sure you recognize that most Resort rooms now have a small beverage cooler these days with no freezer space. They are not ice cold but are perfect for chilling drinks. Plan your purchases so that they can be safely stored in these coolers or at room temperature.
You can find the addresses of each of the resorts on the main overview page for each Resort on the main Walt Disney World site. Make sure to include a note with your full name followed by the word "Guest." Many times there are fields where you can do this or an additional information space for comments or notes. Just an FYI, Cast Members at Bell Services can accept gratuities so consider tipping them if they are helpful.
I hope this helps and you have a lovely time!
Happy Planning!
