My fiancee and I will be on our honeymoon in mid August 2015. We'll be arriving midday 22 and departing on the 24th. I've been to Florence before but she hasn't. I've hired a private driver for the 23rd and wanted some suggestion what to go see.

She definitely wants to go see Pisa and, of course, the countryside around Siena. I was thinking we would go from Florence to Pisa and see the tower and then head down to Siena for sightseeing and lunch at a winery.

I know this will be about 4 hours in a car but I'm trying to make the most of our time and mitigating lost time with the private driver. Ideas? Should we skip something the day with the private driver and something else the afternoon before/after?

Thanks!

I am aware most will disagree with the amount of time but it's what we scheduled and we're trying to make the most of it while still trying to relax.
