Thanks for your replies. The tylenol is more for me and DH. we plan to use water flavoring packets and refill our bottles in the park, so its mostly snacks and sandwiches we need a place for. Thanks again!
Lots of folks do bring sandwiches and snacks to the parks, so you are not alone. Then again, you'll also see folks with HUGE backpacks in the parks, and families with small kids who have no bag at all.
If you reguarly need Tylenol, by all means- bring some. Do what works best for you.
This is always such a personal topic, and there's certainly no one-size-fits all solution of what to carry. My own family varies from trip to trip. winter needs- jackets, even sometimes mittens!- are very different from summer needs- water, water, water!
I'm just trying to impart wisdom I've gleaned from my many travels to the mouse.
If you have a compelling reason to carry sandwiches, by all means. There are lots of good reasons, including saving money and food allergies. Conversely- I don't know if this is your first trip or not - but there is also no shortage of reasonably good, reasonably inexpensive food in WDW. I'd put WDW far ahead of most amusement parks in terms of varitation and food quality. Most other times, I suck it up that the best option is going to be lousy, overpriced cheese pizza. At WDW, you can even get kosher meals, gluten free, nut free, and plenty of vegetarian options. It sounds like you are pretty well prepped, but if you have not looked up menus, you may want to look on the parent of this site or allearsnet for menu listings. (Disney's website does not list QS options). Each park even has fresh fruit stands and all kids meals come with healthy choices like applesauce, grapes, and veggies. Again, I'm not trying to tell you what the best choice is for your group, just letting you know what the options are so can pick wisely.
Have a great trip!
