As far as my favorite relaxing vacation spot, that would be Puerto Vallarta, Mexico. Andrew and I celebrated 4 years of marriage in PV in May, 2008. The entire week was full of relaxation. What a great way to spend a vacation. Lots of time at the pool and on the beach. We also were able to go to a secluded island called Las Caletas, for "Rhythms of the Night." "An exhilarating spectacle, where stories of an ancient civilization are told through live music and modern dance as one of Mexico's most innovative contemporary dance troupes transport you on a magical and mystical journey through time" (Taken from the web-site) There is also a dinner buffet where you actually eat on the beach. It was a great experience.
Another excursion we were able to do while in Mexico was the Canopy Tour. What a great way to see the Sierra Madre Mountains. It was an exhilarating journey as we were able to explore high above the jungle floor via zip lines, suspended walkways and platforms, by scaling the Crazy Ladder and descending via rappels. The whole experience was so much fun!
We ended the week with a couples massage. What a way to end a perfect week!
