14 days is ideal for us. Day 1 is an early start to drive to the airport and fly down. DME to CBR, check in and hit the pool then DTD for dinner. Get a good nights rest. We then have 2 pool, resort, and/ or DTD days inserted in to 10 park days. Last day is swimming at resort then DME to airport. Land and drive home, it's around 11pm. We have done a 10 day, 12 day, and a two short MVMCP trips of 4-5 days each. 14 is our optimum length. Kids still like to go like park commandos but the wife can take it easy, get her autograph items for the trip signed, and just meet us for a meal, shop, or hang out in a hammock. I tend to keep up with the kids.
