We've always found the captains to be very accessible, and there is typically a night - usually a formal night - when you can have your picture taken with the captain.
Every time we have been on board, they have been all around the ship, all the time.
A few cruises ago, I bought the "captains trading cards" framed with a photo of the ship, and at least at that time there were three that rotate - Captain Thord, Captain John, and Captain Henry. We had Captain Thord on our last cruise.
Ooops - almost forgot the fourth - captain MICKEY!
Just curious Mm37, how do you get an invitation to dine with the captain? I know that my DW would really love an opportunity like that!
