So my wife and I want to start walking with the kids to prepare for our trip. We are planning to have two BIG days when we are there, one of which will include a full day at MK then MNSSHP. Basically an early morning until midnight. My kids are not super athletic and I am a pooh-sized individual. So here's the question, how many miles do you think you walk in a full day at the parks? I want to start a walking regiment with the kids so that we feel we can do it all and not kill ourselves, but don't know what our goal should be. I know its a lot of walking, like, lots, but has anyone used a FitBit or similar to know how many miles you typically walk. Kids are 12/9/7 so there will be lots of moving and very little down time.
