San Juan: Exploring the Old City

I decided to try my first cruise this year.  The port of departure was San Juan so I figured that I would arrive a few days early and check out the sites of the city.  I don't think I realized all the history that surrounds San Juan or how beautiful the city is.  My short visit focused around Old San Juan, but I think that's the best of the city.  From battle forts and old churches to colorful architecture and narrow streets, there is a lot of charm and beauty to San Juan.
