On our most recent cruise on RCCL Freedom OTS, we sat next to the Captain's table. He ate at the early seating 3 times that week.
Years ago, we were invited to the captain's table. We were on one of Premier's ships and recognized the Maitre D' from two previous cruises, one on Premier, one on a different and also now defunct ship/line. We introduced ourselves and the three of us discussed those prior ships. The next day, we got an invitation to dine with the cap't. The dinner and service was excellent. Both the cap't and a man I would guess was in his 70s and was traveling alone, were provided with dinner dates so that the table would be girl/boy all the way around. These dates were beautiful, blonde Norwegian crew members.
As the meal proceeded, the lone man took advantage of the cap't's generosity and drank many glasses of wine and mixed drinks. The man's liquid courage began to get the best of him and he became quite twitterpated by his dinner companion. At first he was subtle, but he got more and more overt until he was offering to buy the woman diamonds, a new Cadillac, and a home on the beach if only she would marry him and move to Florida. The woman was ever polite but she was obviously uncomfortable with all the attention. Before dinner was finished, the cap't asked her to go to the bridge to attend to urgent business with the ship.
On another cruise, 3 weeks after 9/11, we booked the biggest suite on the Norway's upper deck. It was $600 pp for a week long cruise and I would guess the ship was less than half full. It's the only time we've ever had a suite, but the price was so low we couldn't pass it up. The cap't invited us and about 10 other couples to his cabin for after dinner drinks. His cabin was four large rooms, with a dinning room that seated about 10, a living room, 2 rooms we didn't see, and a private balcony that was large enough to hold all of us plus wait staff, a half dozen ship's officers, and serving tables. He had a really nice set up.
My in'laws once ate at the capt's table and had no idea why the were invited. The other guests included a US politician, a diplomat from some far eastern country, and a fortune 500 CEO. My inlaws felt like a fish out of water.
