I am not sure when I will be in Florence during my 10 day trip through Italy since I am kinda going with the flow. Is it impossible/difficult to get into Florence museums i.e. Uffizi, Galleria during early November? I hear the lines can be long. Is it still advisable to purchase tickets online for a specific day? I'm on a strict budget as well so would like to avoid any booking charges. What options do I have if I just show up on the day? Thanks for your advice.
