We are heading to Disney at the end of Feb. next year with our 4 children (9,8,5,2) I always over pack and my husband has already told me he was not carrying bags this time. We will have a stroller for the little on. What are the basic must take with us to the parks each day? If I had my way I would have extra change of clothes for all thr kids and lots of little bags of snacks and lots or drinks for the kids as well as a full first aid kit and every medicine that thy may possiblely need. Along with a whole bunch of other little things. What is must have to take That will fit within our stroller?
