Stayed in Puerto Mogan a few years ago. Had a really nice time, but trying to find somewhere to park the hire car was a nightmare. We had to keep moving it from spot to spot, and when we decided to explore the surrounding countryside, the roads were so narrow and twisty, with scary drops, we just we back to our apartment. It would have been cheaper to have booked a taxi there and back.
Nice boat ride along the coast to next village, (Puerto Rico)???
Mogan is not as touristy as some of the other places.
Try and spend some time in the capital, Las Palmas, busy but interesting.
