We will be in Mazatlan in October via the Carnival Cruise Ship Splendor. Our group consists of 6 adults and 6 children (ages 8 thru 15). Which tour would you suggest....Stone Island or Deer Island? My husband, my 2 children and I have been to Mazatlan before in 2005 and did not book a tour. As this was not one of my favorite ports last time I wanted to make sure we had a more positive experience as the rest of our group has never been to Mexico.
