I'm traveling with a group of 6 in January (my in-laws are in their 70's, and the rest of us are in our 30's). I was thinking of doing a private boat because there is more flexibility. Additionally, my in-laws don't really snorkel (so will be waiting on the boat while the rest of the group goes), and even though they can walk around in the stingray sandbar, they may not want to be that close to the stingrays, so I thought we could spend less time in those places, and may be a little more time at Rum Point or Starfish beach. However, the cost of doing a private tour is obviously a lot more, and we would also want a comfortable boat with shade. Do people think that a private boat is worth it? Or are there group tours that would be suitable for us?
