This fall I'm going on a cruise with my brother, niece, and 2 nephews. I'm pretty excited even though it's a ways off yet. We'll be going to the Mexican Riviera via the Carnival's cruise ship, Splendor. The reason why I'm posting this now is that I hope that people who have gone on this cruise will know of all the best excursions to take in each port city. The ports are Puerto Vallarta, Cabo San Lucas, and Mazatlan. So if you have any suggestions, please feel free to share. :)
