Ships' cruising of any vessel description doesn't really do it for me.
Have been on the 'Murray Explorer' twice, & loved those cruises, mostly because it was 'still' water! Same goes for cruising down the Nile River, on a Sheraton ship. It was just brilliant! Very spoilt, & saw all the ancient sites' possible!
And yes, the Cheops Pyramid IS huge!
Only cruise that WOULD interest me, is through the Alaska Passage, on a top-of-the-range vessel! It's on my bucket list!
