It really depends on the trip, so we recommend reading through the itineraries to find your ideal level of activity. That said, if you don’t want to join in on a certain activity, you don’t have to.
To get the best value out of your trip, we always recommend trying all of the scheduled experiences. Instead of skipping an activity, try utilising the free time that’s already planned into the trip.
Got something special like a dive you want to organise? Maybe add an extra day on to your stay at the end, or arrive early.
