I have done 6 tours with 1 booked for this year, they have been different types of tours
Boston New England New york
Nashville and Memphis
East Coast liner
Austrian Lakes
Poland and the tatra Mountains
Kenyan Safari
Tuscany ...to be done this year
The USA tours can be very on the go shall I say, and if your moving on every few days to a new hotel and area this can be tireing...but YOU can sleep when you get home.
Poland and Austria were a more gentle sort of holiday with a bit more free time, which was nice.
I like Mick have never ever had to eat a meal on my own, sometimes I seem to have spent the time away with say 1-2-3 ladies, other times each day brings a new person to get to know, it all depends on where you are going and the group of people who are there.
Pick somewhere you really want to go to and then book it, take a couple of books to read in case you want to be alone, I always do but have never read a book yet, to much to do and see and join in with.
Regarding the meal question you will find someone to buddy up with or the reps ar good at getting people together so NO ONE is alone.
Go for it, they are great fun
