1. We have stayed in that cabin years ago on another ship. The cabin location is very nice, but it is a long walk to the midship area where most of the dining venues. The balcony is very large and a wonderful treat. Be sure to have a sun hat to wear on your balcony.
2. If you really want a suite then I would put in a bid for the amount you are comfortable with paying. Princess will let you know close to sail date if you won the bid. Personally we find the mini suite large enough for two people on a long voyage.
3. Your medallion will arrive about two weeks before the cruise.
4. If Princess says your birthday doesn’t match their records then I would take the time to call them (and wait on hold a long time) to be sure all important info is correct.
5. Yes, you can use the app to book specialty dining. If you have Platinum or Elite status you can book dining reservations before final payment. IMHO I would make reservations in a dining room close to your cabin if mobility is an issue. There is one dining room in the aft of the ship.
6. The sanctuary is an Adults only pay for a lounger area. We really like the pampering we received and enjoy this area on Sea Days.
7. The dining room is my go to for food unless I have an early excursion then I’ll pick up breakfast at the international cafe.
Have a fabulous cruise, that is one of our bucket list cruises too.
