Ciao all. My wife and I will be exploring the Tuscany region for 7 days starting Sept 19th, 2017. The pragmatic planner in me says in order to assure us of accommodations and at the best price we should book now. The spontaneous romantic wants to go where the wind takes us. While I am adventurous about where I stay (mostly clean hostel? Cool...), my wife requires refined lodging. So just plopping down on a locals couch is NOT an option. Question: What percentage extra should we expect to pay per night and what reduction in availability/choice will we experience by booking the same day? Thank you in advance for any guidance.
