We will be arriving in Florence on Monday, Sept. 10. We are very excited to finally visit Florence and have several questions. What are our options for getting to our hotel (near Piazza San Marco) from the airport? My wife and I will have one medium sized suitcase and a carry on. I can purchase a two day Hop On Hop Off before we leave, but if the price is the same I'd prefer to wait. Any price advantage in purchasing early?
