A friend had just told me of a TV show "Dream Cruises" on AWE channel. Each show is 1 hour and is on a cruise, Everything from Carnival, MSC, Celebrity, Fred Olsen and river cruises I have not heard of. The show is like a documentary showing you the cabins on the ship, ship activities for sea days, where to eat on the ship and they show you all the ports that the cruise stops at and the excursions they went on.
For me this is a 1 hour vacation. Not all cable providers carry it. It is # 387 on Direct TV. I know Spectrum does not carry it and on Roku it is about $ 3.00 a month.
Here is one episode that made it to YouTube https://www.youtube.com/watch?v=u8uUFS3OtKQ
