Wow, you wouldn't cut it flying overseas with us. We flew to Paris, by way of London, got to the hotel at DLP and room wasn't ready and then walked DTD until we could enter the park at 1:00 for free. (I was a CM at the time and that was our restriction to get in the park for free.) Stayed in the park until it closed and finally got back to the room around 10:00. Did the same thing last year when we flew to London, only difference was we could get into our room at 8:45am, then toured London until 9:30pm.
Yup long days but worth it and NO we didn't have the laydown beds in first, just the no leg room in world traveler on BA. I wouldn't want one of those sleeper first class seats on a flight that short, I'd rather have it on a much longer flight like going to Australia, but that won't be happening as long as those flights are around $18,000/person

.
I'll stick with my overnight flight and catch a little bit of sleep.

But then there are only 3 of us and it's easier for 2 adults to keep 1 child entertained & content on a flight, unlike your clan.
