I will be in Florence next April for 3 full days before taking the train to Bologna for a day (staying 1 night) and continuing onto Venice. Already planning to see Florence for 2 days and spending a day-trip to Pisa/Lucca.
I also have the option to forgo Bologna and stay in Florence one more day which I would use for a day-trip to Siena. But I heard Siena may be similar to Lucca. What are people's thoughts about either Bologna or Siena? Thanks
