True, the flights will be full as they're thirteen seat aircraft shifting a 200 seat Intl. Jet passenger list. Water Taxi can be, but less likely, just as packed if not worse, with little regard for max passenger numbers. I'm 6'4" and 200lb and it can be a little tight but I've seen much larger people regularly do it and it's twenty minutes of discomfort with the worst of it just getting into and out of your seat. At least you now know a bit more info to make your choice.
