We are travelling from Canada to Disney in May with our six year old, four year old, and seven month old. Any tips to make our trip easier? I plan to bring a moby-wrap and a lightweight Combi stroller. I was also planning to rent a stroller at Disney for my four year old, if he gets tired. Also, what is this Green Grocer that ppl are talking about? Will they deliver groceries to our house off-Disney? Thanks for any tips and advice.
