We drove last time we went. We actually drove down and took the train back. I like it, my my dh said he didn't sleep well on the train. I just don't look forward to lugging 2 preschoolers, a double stroller, 2 carseats and lugguge through an airport.
On another note, I'm not sure what we are going to do with the twins for sleeping accomadations. We are staying in a timeshare (thanks to my mom) so we have 2 bedrooms (3 beds and a pull out sofa), but the twins sleep in kind of a converted crib now (with side rails so they don't fall). I tried having them sleep in a double bed once this summer when we went on a small weekend trip and I spent the entire night waking up and moving them back to the middle of the bed. I don't know if I should just get them pack-n-plays or try to see if we can get bed rails for the bed or what. When my older son was 3, we just put him in the middle of a double bed and he was fine - never moved enough to get close to falling off the bed. Two of them is so different. Anyone have any tips with 2 three-year-olds?
