You'll not be charged per person rather it is based on the boat. You can also hire boats at the S-curve if you're not planning to stay on Munroe Island. You'll find boatmen at this point offering different boat services. The rates will keep varying every year/season so it's always best to contact your homestay/resort to know the latest rates.
