Hi Lorraine,
Welcome to the world of single travel! I do hope you have a wonderful time on your first trip with us.
I thought I would dig out a couple of posts that you might find useful.
First - this post was from one of our Tour Managers who operated this tour last year - before departing she posted some hints and tips that you may find useful...

Second is a review from Bob, one of our regulars on the community. He took this tour back in 2014 and wrote a very comprehensive review on his return, this will help give you an idea of what to expect.

I'm sure reading through the threads on the community, you know that you aren't the first person to feel nervous before taking this type of holiday, and I'm sure you won't be the last either!
If you have any questions, please do not hesitate to ask.
Kindest regards,
Julia
