Dear Betty Lu:
So glad to hear from you.
Re: finding the number of attendies for the cocktail parties. . . you are not doing anything wrong. You will get an email update every Monday which shows all of the cruises, their current count and the person who has agreed to be responsible for name tags.
We are arriving on June 13 and will spend that night in Dover. We want to get back to Dover Castle. We visited the underground tunnels when we were there in September, prior to our Dover-Barcelona cruise, but didn't leave ourselves enough time to see the older parts.
I think we will do the larger cities on our own, using hop on, hop off, buses where available. Don't know about the more rural stops in Scotland. I expect this will be a less intense touring experience than some of our prior trips. And, that's not all bad!
