Coming to Cancun w/husband and child 6yrs old. Flight doesn't arrive until 7:30pm. Was thinking about taking a taxi from the airport to the Westin where we are staying. My understanding is that it should be about $25 since we are just about the first hotel from the airport. Question is, is there an OXXOS where we can stop along the way to pick up some bottled water/cokes? I understand there isn't a market close to the Westin and we will be leaving on a Chichen Itza tour at 7:30am the next morning, so I'd like to have some cokes etc to take with us. Is that doable? What should it cost to ask the driver to make an extra stop? Much appreciate the help. We are coming in two weeks and are counting the days.
