When I plan I do it all myself and these are the resouces I use. You need to check them out if you are planning your trip. They will save your life and sanity.
This is the best restaurants at Disney Springs or right next to all the Disney things.
Snacks in the park are obviously why I even show up but they can get expencive. These are some of the snacks I take in my Disney bag.
You need a go-to bag to take to the parks. Trust me. Make sure you take a bag that has all the space you need but also compact.
