We're a party of 8; 4 elementary school kids, their parents, and Grandma and Grandpa. Feeding this entire bunch will be costly to say the least. To complicate matters, several kids are on very restricted diets. I understand there are locker rentals at MK in the train station? Do they ever run out of lockers to rent? Does anyone know if there are locker rentals at MGM, EPCOT, and AK? We have 2 nice size collapsible coolers that we could take but we don't want to haul them around all day. We'll be there the first week in October (school is out for fall break) - really looking forward to the grandkids first WDW trip!! Thanks for any suggestions.
