I agree, San Juan is a magnificent city. We love to go to Restaurante Baru for a tapas dinner that will knock your socks off. Oh I wish I could go today.
Mexico is a wonderful country too! And the Mexican people are so very kind to Americans, even when these acts of kindness may not be deserved. I have traveled to most of the major cities and am planning to go to Oaxaca in April on a land cruise. I've never been short of things to do in Mexico. Ever!
Maybe one needs to do more homework before he or she visits these places and them you will never be bored, I promise!
Our favorites in Mexico so far are Puerto Vallarta, Copper Canyon, Guadalajara, & Puebla. We also enjoyed cozumel and Isla de las Mujeres. We can hardly wait for Oaxaca which is the culinary and arts capitol of Mexico.
