Thank you for the all the good information. Our passports are already the extended 52-page version, and they are good until 2026. Currently, I have about 20 pages left in my passport, and my husband has about 25 pages left. (This will decrease with upcoming travel in 2022.) I am deciding if we need to 1) apply for a new passport, 2) get a second (backup) passport, or 3) take our chances that our existing passports have enough pages. Given the amount of time it takes to get a passport renewal, and our other upcoming trips, there is not a long-enough time window when we can be without our passports for the renewal.
Oceania's VISA PDF for the 2023 World Cruise says "NOTE: Guests are required to have minimum ten (10) blank visa passport pages at time of embarkation to facilitate passport stamping, including South Africa. South Africa port officials alone require a minimum of two (2) blank visa passport pages (one upon entry to the country and a second upon exit).
Ten blank pages does not seem to me to be enough. It may be enough for the VISAs
only, but what about country enter and exits.
So... if you took a previous world cruise, how many passport pages did you actually use? And, did each country you visited stamp your passport if you left the ship?
Thank you again for your insights and sharing of information.
