I usually spend my time in Akumal and Tulum but as they grow I've been curious about PM and am considering a stop for a couple of days in September before I continue further south. I travel solo and would welcome advice on non AI hotels that are within easy walking distance (no car) to the center of town and either on the beach or very close by. Since it will be September, perhaps a place with a/c would be a wise choice. I've sweltered in Tulum in September without a/c and would rather not do that again. I'm not adverse to simple accommodations as long as the room is clean. And I would especially welcome any advice and tips concerning "don't miss" things to do and restaurants.
