Beautiful views, open bar, 3 levels of different entertainment! Not a party booze cruise though, just locals and mostly Mexican tourist having a fun, it was perfect. Don’t expect staff at the kiosk or on the boat to explain things to you in English, enjoy the chance to practice your Spanish - though you will still have a blast even without understanding exactly what’s going on! Book at least a day in advance. I booked the same afternoon, and only just got on the boat 5 mins before departure as the office at the ward had not received (or checked with GYG) the tickets, I brought the print out of my voucher but The lady in the kiosk looked like she’d never seen one before. Still, I caught the boat just on time!
