We had 10 people and 2 dinghys and thought it worked out very well. If we were just had to worry about making two trips to shore all the time it wouldn't have been as much of an issue but it was nice to be able to go farther away without feeling like you stranded the rest of the group. We had two families - 4 adults & 6 kids. The older 4 girls often wanted to go explore, go snorkel, go to Bubbly Pool, etc. while the younger boys sometimes just wanted to chill on the boat or on shore. It was nice to be able to leave some adults & kids behind knowing they could go somewhere when they were ready, we didn't feel like we had to rush back to check on them.
