Lynx 42 then 111 change at bus station or num 8 then 50, change at sea world will both get u to ticket and transportation centre. Sometimes we got off at down town Disney and took contemporary resort bus and did 5 min walk to mk from resort! Easy. On lynx ask for transfer ticket and it's 2 dollars each way per adult 1 dollar for kids. 0n late nights we used king solomons shuttle Paul is a great honest guy who will always turn up. He charges about 12 dollars per peron for a shuttle back to hotels on I drive .
Food wise lots of choice there is hotel buffet which looked popular or there is sizzlers etc across the roads there is fridge and microwave in room . We used Walgreens across the road or we ate brunch when out. As we like to be at rope drop ;-)
Just arriving at my UK home now so will answer any more question quicker and better on laptop . First a big sleep !!!
