I think elderly accommodations on cruises will vary by cruise line. I suggest you contact specific cruise companies to ask them their policies on elderly accommodations on cruises. Before booking any cruises, make sure to double-check that those accommodations are in effect on those particular cruises. Good luck!

Hotels have the same accommodations for the elderly as they do for persons with disabilities. Rooms on the ground floor, with easy access points, shower seats, TTY, non-smoking, are just some of the options available. Use well known travel sites such as kayak.com that list accommodations as well as call the hotel in advance and discuss personal needs with the staff.
I find the best deals for Alaskan Cruises can be found at Expedia dot com. Expedia has a complete package that includes the cruise and hotel accommodations.
Amtrak provides price accommodations for the elderly. If you want to ensure that your grandfather has a comfortable trip, I would suggest that you buy him a first class ticket.
