My wife and I will be at the GS from April 11 to 17 and are planning to rent a car for a day or two. I have rented cars and driven in the area a number of times and am comfortable with doing so. We would like to to to Coba for the morning and to Tulum for the afternoon. We know the Tulum beach area well and if you have never been there it will blow you away. Anybody intrested in sharing the cost of gas and rental for the day let me know. It shouldn't be more than 40.00 dollars.
