When I took this tour in 2015 it was $80 per person, which was almost double the cost I paid for tours on other islands. St. Maarten and St. Kitts were both $45 per person but they were not booked through the cruise line. So even at the time this tour was more expensive than your average island tour. I did think it was worth it at the time, especially since there were pretty limited options at this port and it really did turn out to be a fantastic day. They took us out one way (through the jungle) and back to port a different way (along the coast) so both ways you had different scenery which I liked. I just went and searched and it looks like Princess is charging $100 per person now, so that doesn't seem out of line compared with the 2015 cost (not with how bad inflation has been the last couple years, anyways). I'd happily pay that to do this tour again.
