Im scared of flying and 17 hours to thailand is a lot but willing to do it if its good
It's been awesome...weather, sights, people, even food.... but mainly this resort. For the 7 days we've been here, we haven't left the premises for 4 of them and that's very unusual for me as I'm a very restless person. I rarely go back to a long-haul destination twice (too many places in the world to see in such a short life!) and so far only New York and a California/Vegas flydrive (done 3 times and counting) has tempted me back more than once. I'm confident that this place will be added to that list!
Flight is only 11 hours so only 3 more than you're doing to Cancun (also, that was to Malaysia which is a bit further than Phuket).
Anyway, if you've booked Cancun you should like that...it's one of those places you can't fail to enjoy really!
