Can I come on the boat more than the number of people in my reservation?
If more people come to the boat than they have rented, you must act in accordance with the agreement. In this regard, the owner of the boat may request you to be in the agreed number of people or an extra fee. The decision process is at the boat owner's discretion.
If you discuss this situation with the boat owner at least 24 hours before the start of the tour, you can eliminate the problems that may occur. Since the boat owners prepare according to the number of people, even if you offer an extra fee, they may not be able to host your extra guests.
