I love Mexico and in the past 10 years have been there more times than I have been to Jamaica by land, air, and sea. It's really a more relaxing vacation for me plus they think it's cool that I 'know' Bob Marley:-) We stayed in Playa del Carmen but visited the ruins in Tulum, climbed the one in Coba, and spend the day in Chichen Itza....wow! I love the history, the food, and the top shelf liquor at the cheap resorts:-)
My goal and desire is to see the world, not only a country. However one of the countries I fancy seeing most is the good old USA (Hawaii in 6 weeks). What amazes me about Jamaica is most of what I travel to see in the rest of the world is right there. I often feel the further I travel away from Jamaica is the closer it takes me back.
IMOP, if you keep going back to the same place, without experiencing others, it can easily close your eyes to the reality of the place, which includes the beauty. I have noticed this with some of the Negril addicts and Sandals/Couples fanatics.
