Thanks to all !
We will not join flotilla sailing, don't think it will be fun, though I admit, none of us have ever tried.
Yes, I have looked at all the itineraries of charter companies, i have found. There are thousands of them. This is why I am asking here, because, we know, their point of view often differs from ours
I will look these to companies now.
If there are some other suggestions - more than welcome.
