My husband and I are headed to GBP Coba May 9, we have been to GBP Ambar and Runaway Bay many times but this is our first time in Mexico. We would like to go to the Akumel beach and also the Tulum ruins without paying the excursion prices. I have read many reviews all about the collectivos and taxis but I'm not sure which is best for each destination. Any recommendations as to which would be better for us, we don't know the area and our Spanish is a tiny bit better then basic. Is it a long walk from where the Collectivo drops you off, and approx. how far is Tulum ruins from Akumel beach and how far from the GBP are they. And last but not least, is Akumel beach in or near Playa Del Carmen, would like to do shopping there, so any tips about this or anything else you can think of for a vacation in this area would be greatly appreciated.
