Yes 6 hours is a long time to be on an airplane even without two little kids. But we made it! Henry enjoyed the flight with way less " reading material" than we expected. Lucy slept 3 times, but cried for a while before each nap. All in all, I'd say it was a success and now WE ARE HERE! Day 2 and all a little sun-touched. Today we have a cabana rented for some shade an ocean view and 10 feet from the bar. Ahhhh.
