Hi Michele,
As much as I love Walt Disney World food (did someone say Dole Whip?), I've always appreciated that the theme parks allow you to bring your own snacks, non-alcoholic drinks and even meals.
This was especially essential when our daughters were young so that we always had a box of juice or some cheese crackers within easy reach. Even now, I usually stash a protein bar or a small bag of trail mix in my bag for the times when I need a little energy boost before my next spin on Big Thunder Mountain Railroad, Test Track or Slinky Dog Dash.
There are a
few restrictions on what you can bring in, mainly no glass except for baby food containers and no outside alcohol. And, of course, no illegal substances are allowed. The page I linked also will give you the current restrictions on the size of coolers, bags and strollers, something to consider as you decide how much food to pack.
We usually keep it simply and light: a few snacks and a water bottle or a sports drink. But I have seen families bring full meals, everything from a loaf of bread, a jar of peanut butter and a bag of chips up to a three-course, home-cooked meal unpacked from a soft cooler.
If you are looking to economize, here's another tip: Every quick service location throughout the parks will give you a free cup of ice water whenever you need it. There are many water fountains, usually near restrooms, and the parks are adding a number of bottle filling stations with filtered water, even in some of the ride queues.
Thanks for your question, Michele. Please let us know if we can help in any other way as you plan your visit. Enjoy!
Wilma
