We are going for our 1st Disney trip next week and will only be able to go to MK 1 day. I wanted to bring in lunch but not sure if they allow that? We are on a very very tight budget so I need to be as cheap as I can be. What about coolers? Do they allow you to bring these in and place in the lockers? Also, same for Seaworld and Aquatica. I know Aquatica does not allow any food at all but what about Seaworld? How far is the walk from where you park to the entrance? Is it feasible to leave a cooler in our car and just go out for lunch? Thanks!
