we went across the atlantic and for ages were flying over newfoundland, then we went down the west coast of the US, it took 9.5 hrs. coming home we flew over the blue ridge mountains of virginia (in the dark) and back across newfoundland and it took about the same.
go to the coco bongo club but don't buy a shot off the girl with the whistle too expensive,
Try to get to chichen itsa, long monotonous coach trip up there but stunning when u are there.
Took us about 11 hours from Gatwick to Cancun with MyTravel. If you're flying with mytravel it's worth upgrading to Premiargold for the flight. The extra legroom, wider, more comfortable seats and dedicated cabin & toilet were a godsend!
