We found getting on and off the boat was the biggest issue. Parents used a baby carrier for that, but pretty hot to use the rest of the time; a cheap stroller might be a good idea, but remember roads and areas you are going to use it aren't that smooth! we had a cheap bouncer chair, though he was a little younger than your boy, and then donated it t a charity when we left. Could do the same with a stroller if you don't want to bother taking it home.
