My son is desperate to do do this trip , as am I. However, the information from Thomsons states this trip is not suitable for non-swimmers. Neither of us are strong swimmers but love boat trips, and my nature loving son particularly will enjoy the glass-bottom aspect of the boat, and looking for dolphins. Has anyone done this trip before and can maybe give me some feedback about it. I know there are other boat trips available and we intend to try them too but would really love to do this on too as it looks like it would be a brilliant day out. Thanks in advance.
