Starting to look at the details. I booked the Gray Line meet and greet concierge van offer from Orbitz when we booked the trip. I was sure it was a round trip then, (I am confirming). Just it seams a little vague on getting you back to the airport in time to make the Boston flight home. We land at Cancun 11:40 am on saturday march 8th for Riu PM. Departing flight takes off following saturday march 15th at 11:40 am. Cost 268.00 USD for four of us. 67 bucks per person. Package says the van will never load more than seven people. Any one have problems with Gray line. Is it pretty easy to get a ride back to the air port in time for your flight if something goes wrong. What is your preferd way of getting from and back to the airport.
