The advantages of the giant paddleboard over a kayak are many.
You get to stay with your group on one board for a shared experience.
You can stay totally dry if you choose. That saves you a trip to your hotel before and after since you can come dressed as you are and go out straight after the tour. This saves alot of time and money.
You can stand up, sit down, or lay down. The combination of all the above makes a way more comfortable trip.
There is no weight limit and these boards are ultra stable. Sometimes people are afraid of the word "paddle board" but take whatever excuse you have for not going on one of these and reverse it and thats more true. "I don't want to get wet." --- Actually you get wet on a kayak but not on a giant paddle board. Thats true for almost any scenario you can think of.
