Thanks for the input.
The irony is I just had a conversation with a friend who is going to Europe (non moto vacation) and I was giving the same type of advice....better to see a few things well than a lot of things barely.
Does anyone have an idea of what a minimum would be to 'comfortably' cover the distance?
Again, I realize this is all extremely subjective.
The idea of renting bikes while down there has indeed occurred to me and I may go that route. I'll give it some more thought.
Thanks again for the input.
