Hi Ames,
Anytime around 12:00 noon is a good time to arrive at the pier. If there are any shore excersions you want to do you can pre-book online at the Princess web-site, nice feature. You can also check your booking, but you need your booking number from your travel agent or by calling 1-800-Princess. By having all that information completed, makes boarding quick, we did have the express check-in and it only took about 2 minutes and we were boarding, it was great!
Have a great Princess cruise.
