April 6 is our departure date for Istanbul, no cruise involved, I think is possible air travel to Europe will be curtailed by then. I guess our cruise in September will be OK. I have not yet made air reservations, and can delay the cruise if needed.
That one is in the Baltic and I was looking forward to visiting Russia, Finland, and Sweden. The wife has a good friend in Sweden and we were going to spend 4-5 days with her.
