Thanks, fed, for your good wishes. I'm eagerly looking forward to the relaxation of the riverboat as well as the sightseeing. It's been many years since my last excursion overseas.
In part, I share your wife's phobia about deep water. Only, in my case, it doesn't bother me if I'm well above the water, such as on a ship or large boat. I've even been comfortable on a catamaran in Hawaii. But it took great resolve to jump off that catamaran into the ocean to go snorkelling. Several times in the water, I panicked and had to calm myself by watching the fish. If my focus went to the ocean floor, the depth of the water was frightening. Stupid, I know, but I guess that's the nature of a phobia -- irrationality. My husband and son both loved the water but were patient with my fear.
No fears of anything worse than jet lag this time!
I've been following your chat with Mike on aircraft. If my husband were here, I know he'd want to join in. He was a navigator in the Navy and had a private pilot's licence a long time afterward, always loved planes and flying. But my ignorance is as great as was his knowledge, so I'm silent there.
Thanks again -- best wishes --
