This is our fourth time to the Mayan riviera. We have stayed at riu resorts twice and the Bahia principe Tulum. We have chosen the Via Wyndham Azteca this trip, as we could not pass up the great deal. We are two families.....four adults/3 children aged 11, 10, 9. We have been to xaret (with kids) Xel ha, cozumel and Tulum without our kids. My question is....for excursions we are planning xel ha...not all inclusive, so that the kids can swim with the dolphins ( and still stay within our budget) We would also like to take the ferry to cozumel, and maybe cab it to a beach worth snorkelling. Any advice??? Re: beaches in cozumel. Approx cab ride to xel ha from Playa car Also any idea what the exchange rate is currently....US Dollars to mexican pesos??? Thanks in advance. So excited to be going back!!!
