My family has visited Cancún since the 1970’s. When I was a teenager I loved to hook-up with Argentine and Paraguayan girls my age who would be coming over as it was quite cheap for them back then (in the times of the convertible peso). Now, a quite easy visa regime and direct flights mean that in the Mexican off-season after January 6th it’s chock-full of Russian and Brazilian tourists besides a few Americans & locals. Wouldn’t be surprised if in a few years the Chinese start holidaying there too.
