Great idea and you’re thinking in the right way. I recently did exactly that through tropical island escapes https://charterclick.sc/our-services/yacht-charter-praslin and it was effortless. The site shows real-time availability, clear pricing and you can pick a yacht based on group size, route and extras (skipper, catering, snorkel gear). What stood out was how customised it was — we told them we wanted to focus on snorkeling spots and calm anchorages, and our skipper planned a route through Curieuse and St. Pierre accordingly.
