Just came back from a great holiday in Cancun Mexico, if you have never been then I can certainly recommend a trip, the people are very friendly, though they are really poor, it is such an amazing contrast to the USA. I went in February 2017 and the weather was great 29/30C every day and great sun. The beach front at Cancun is really nice, with Palm trees and full of people having a great time.
I can honestly recommend a trip, the only downside if the long flight 10 hours from the UK, which with young children was a bit tough, mostly for the wife!
Returning to the UK was a shock as it was zero degrees and snowing, with more snow to come the rest of the week!
Anyway back to work and dreaming of the next trip!
