Hello lovely people,

Me and my daughter are visiting Florence next week. I need your help with itineraries:

a. We would like to do day trips to Pisa, San G, Bologna and Siena. Should I book a tour or just do them myself? Are the bus/train prices very expensive?
Note: I am planning to buy Interrail for 7 days for myself. I see Trenitalia offers free travel for kids under 15 with the Bimbi card. Can I buy this after I reach Florence?
b. We want to visit San Marino but as a day trip from Florence. Doable?

c. Any other advice? I am looking to stay at an AirBNB close to main station so I dont have to spend a lot of time reaching the bus/trains.

Thanks a lot!.
