Hi Connie,
As I wrote in an article last year and that will be featured again soon in a revised state, no one, whether a child diagnosed with ADD or not, if they have an aversion to crowds beyond belief, unimaginable congestion, unsafe road conditions, garbage piled about, and high prices, should visit Mexico's beach resorts during "spring break."
Great tips, Connie. However, you might be wise to add "STAY AWAY FROM COASTAL MEXICO at that time!"
