If you went to Cancun area and only rode Tulum, you missed Isla Blanca, waves in hotel zone of Cancun and many other spots, Tulum is lightest spot in whole area. I lived in Cancun for many years and must say you blew it

. Many people ride the flat water at Isla Blanca and say it is one of the best spots they ever rode. Tulum is good for topless chicks like you said, chasing backpack betties at hostels and seeing the only Mayan Ruins in front of beach in the area. Water is some of the most beautiful in the area but wind is usually more than a few knots lighter than in Playa to Isla Blanca area. COntact Ikarus they will hook you up, Foca is the coolest.
My 2 cents.
