Many thanks for leaving your review, we are delighted you had a good time in Mathraki. Your suggestions are really helpful and we will make the departure point clearer in the trip notes and the pre-departure email, although the local buses can be a tad unreliable which is why we don’t always recommend these to guests trying to catch the hotel taxi boat on the day of departure.
Partners and non-swimmers are of course welcome to join in as much or as little as they like, and are welcome on the boats, which most people enjoy. Otherwise, you are right - relaxing, reading and walking is the main order of the day for non-swimming guests!
