Hi, don't know how old your girls are, but we went to mexico at easter with our 9 yr old daughter, we chose the hotel because of the waterpark within it, 17 different slides, though may not appeal to teens. The hotel was like a village, 9 restraunts and 11 bars, absolutely awesome ! its an eco resort, so there were loads of wild animals roaming around, like raccoons and spider monkeys in the trees .
we would definately go back there and thought it was well worth the 10 and a half hours flight.
cheers,
juby

i love the idea mexico, one is 4 and twins are nine. I was more concerned of the long flight and only being able to go for one week though
