I cannot speak to Princess Lines experience but I can help in the Vancouver Aiport as I live in BC and travel back and forth.
First here is the website for Vancouver Airport and it is informative and contains a section on CRUISE passengers, what to expect. Please read it as it is detailed on the steps.
- VANCOUVER Airport is undergoing some construction in the domestic area and they recommend you allow for time. Local flights they suggest two hours from the norm of one hour.
- An Airport User Fee exists and must be paid prior to going through security to board your plane. Its not in your plane tickets cost.
You can purchase your AIF ticket at a staffed counter located in front of security or from an ATM type machine near the stores and the counter.
Its $10 CDN
- US Customs pre-clearence is done at Vancouver Airport which means you check into your airline counter and then take your baggage through US Customs, its then put thru to your airline.
- Its a large airport but the signs are well layed out and the US section is not hard to miss also you will fill out a US Custom form.
- The Vancouver Crusie Port handles the Bus and baggage very smoothly with the various cruise lines. Once cleared off the boat , you would proceed very quickly. Its about a 20-30 minute bus ride to the airport and I presume you are using Princess transfers.
Taxis are about $20 and same time.
- Ensure you tell your cruise line you need to be off soon to get your plane and you are travelling with your folks.
hope I've helped
