Hi Stormy and Peter,
If I am to assume that both of you are asking about assigned dining on Golden Princess,
don't worry! Wife and I did Grand Princess,
the same sister-ship lay-out as Golden and there are no problems with staircases.
There are two separate dining rooms, one each on Fiesta Deck 6 and the other on Plaza Deck 5. Both have own entrances, all level floor and perfectly accessible for the wheelchair. As far as I know, Princess is the only Cruise Line that does assign HP people to a more accessible dining room location, easy to get in and easy to leave. Contrary, I remember, on Summit-Celebrity
they placed us in the dr corner, which meant- to get there early and leave last... in order not to disturb other passengers.
Golden is one great vessel and wife and I encourage both of you to book the cruise ASAP, you will love it!
Vladimir and Elfrieda
