I went on a Mexican Riviera cruise over 10 years ago. There aren't many historic attractions so you'll want to ask the shore excursions desk to recommend a good beach your family can taxi to or spend a lot of money on shore excursions sold through the cruise line! Unfortunately, we did experience some rough seas that cruise. Hopefully that was a fluke and that you'll have smoother seas!
How old are your children? RCI has a good kids/teens program.
