I JUST returned from an awesome trip to Cancun and surrounding areas. The 45 minute bus ride down to Playa was fine. Returning though, the Federales had set up a checkpoint, and our return bus ride at 5PM took OVER 2 and a half hours!! They funneled all traffic to ONE lane and stopped every vehicle. The check point the next day was checking traffic both ways. Plan accordingly if the checkpoint is still in place. There was NO announcement on the bus so this was a total surprise to me, and I did miss an appointment. The only small glitch in an excellent vacation.
