If you have arranged for someone from Princess to meet you at the airport with your travel agent, then you may be able to get on the ship shortly after you get out of the airport. If you made arrangements yourself, then you are on your own to get to the ship and board. We were in the Panama cruise and made arrangements to arrive to day before, so all our hotel, transport and boarding times were arranged beforehand.
Please check you Princess Package, or the one your travel agent provided.
Have fun on the Princess cruises., Let us know how it goes.
