In case you guys don't get over to Kabah and La Luna, they have opened the new La Luna extension. If you are coming from Costco, you can make a right at the light at La Luna, and go past the new stadium. The new road ends at Xcaret and La Costa, where the police cars used to park. This is a time saver to get away from the Kabah traffic at peak times. I am pretty sure it just opened on Saturday as I remember a bunch of orange traffic cones (now there is a new concept) until some time on Friday or Saturday. Enjoy.
