Well Done Debie - Go for it.
I used to go, on my own, every September for one week. A very good way to unwind etc. It's accepted more and more now that,very often, people like to be their own company but, years ago, when I did it, there was always some kind person who liked to take you under their wing. You will find plenty of friendly people to talk to, if you do get bored. If you are going before the end of July then go to Brouklis one evening and say hello to Hanaka. A very nice Dutch Lady who, like you, is an independant traveller. She asked to share our table one evening and very good company she was to!! Lots of Laughs. Her English was better than mine as well, so no communication problems.
Have a good one but watch out for those smooth talking Greeks.
