You say you are in a wheelchair. That being the case one thing you should be aware of is that in Ketchikan the tide rises and falls 30 feet. You may leave and enter the ship on different decks. Every ship I have been on they do assist people in wheelchairs going up and down the gangways.
They do move the gangways several times during the stop in Ketchikan. So you may have a steep or slight slope depending on where the tide is at. As I said they will have people assist you I just wanted you to be aware of it.
Do not worry about tenders or the ramp angles due to low ar high tides. The only other stop that is tendered is Sitka (I am not sure if Princess still goes there) but in any case, my wife is also in a wheelchair and we have been twice to Alaska. The crew is very helpful and one way or other, they will assist you off and on.
In fact there are other smaller boats (up to 24
passengers) that we recommend you take to view some awesome out-of-the-way places - and the crew will help you board it without any problems and even put you on the bus back to the vessel.
Have a fantastic cruise and let us know how did you like it.
As long as they have some handrails i should be able to get off, i can still walk a little..(Thank god). I am very excited about this cruise.. Last year we did the Sea Princess to Hawaii, 10 days, it was GREAT. Tryin to do it all before i'm totaly wheelchair bound
