Since you won't be clearing customs in Los Angeles, go ahead and put your cruise luggage tags on your luggage before you check it for your flights -- and make sure that airline's check-in agent does not remove them when when you check your luggage! (They sometimes instinctively remove "old" luggage tags without first verifying that they really are old.)
Upon arrival in Los Angeles, look for Princess representatives as you enter the terminal. They usually try to meet passengers at the gate. If you don't find them there, continue toward the baggage claim until you find them. They usually wear blue sweaters and white pants or skirts, so they are pretty easy to find. Also, the Princess representatives usually carry clipboards with a huge Princess logo (blue and white) on the back -- and they hold the clipboards high to flag arriving passengers (when they are not looking at their paperwork). When you find a Princess representative, he or she will provide further directions.
>> Regarding luggage, practice does vary. Sometimes the representatives will direct you to claim your luggage and put it in a specific place in the baggage claim area. At other times, Princess representatives get the luggage directly from the airline. From there, Princess usually loads the luggage onto trucks for transport to the ship.
>> Once you have done whatever you need to do with luggage, the Princess representatives may direct you to a hospitality suite to wait for your buses, or they may simply show you to a meeting point and give you a time to meet there to board the buses, or they might send you directly to a coach. In any event, they will get you onto a coach headed to the ship.
Note that your checked luggage will not travel with you to the ship, and that it might arrive in your stateroom a couple hours after you do. If there's anything that you think you will want on the day of arrival, pack it in your carry-on luggage.
BTW, I just found the list of shore excursions for this cruise on Princess's web site -- and it seems to have expanded considerably since I took a "Mexican Riviera" cruise aboard sister MV Sun Princess three years ago. Here it is.
>> SJD-X Cabo San Lucas Certified Dive (3 3/4 hours, $81.00)
Overall, this looks like a reasonable variety of excursions. You should receive an information package about sixty days before sailing, or soon after you submit your final payment, that will containing a booklet called "Adventures Ashore" that will have detailed descriptions of these excursions.
BTW, which date are you going? I'm going on the 3rd of November.
We used transfers in LA on our 2000 Elation cruise,all I can say is I'll NEVER DO TRANSFERS AGAIN!
Absolutely no organization.....total chaos.People getting on the wrong buses for the wrong airports.....loading and unloading bags with one driver trying to sort out the mess, the process took nearly 2 hours.
We've booked the Star Princess March 2002 and this time we'll get a limo/ taxi to and from airport/port & I don't care how much it costs.
