bus to and from ship to end of pier

the free bus from the ship to the end of the pier....how often does it run? I'm thinking about gettingn off and just shopping and maybe hitting the beach nearby, i just don't think i be ashore for 6 hrs. i be thee and back in like 2-3 hrs. Will the bus bring me back even if it just like 5 people waiting to go back to the ship??

The free shuttle runs every 10 to 15 minutes or so.

Free shuttle bus service is every 15 minutes as long as the ships is docked, the last one leaves downtown Progreso 30 minutes before the ships departure. Enjoy Progreso.
