Does anyone know what the difference between ship time and Mexico time will be on the Mexican Riveiera cruise ?  We are going on the southern route, Acapulco, Manzanillo, Zihuatanejo/Ixtapa.  It looks like that area is two hours ahead of SanDiego time where we depart from.  However, is ship time also San Diego time?  The times listed for each port are based on ship time, right.  We are trying to book a private excursion, but want to be sure that we don't miss the ship.

Every cruise I have been on, ship time has been the time where the ship departed from, East Coast for us. We maintained that time for the entire cruise. Once on board, I know there were clocks on the lido deck by the pool. I would simply set my watch to that clock and leave it there for the entire cruise. Hope this helps. Happy Cruising!
