I found the forums really useful when planning my trip so I thought I'll share my travel experience in Florence recently. My husband and I and our two children were there recently during the Culture Week, so our entrance to the Accademia was free although I booked online and had to pay the booking fee. It's recommended as there is a long queue outside and all I did was to show our booking voucher and we were whisked in. David is really worth it but so are the unfinished Prisoners.
We did not go to the Uffizzi as I felt that too many museums would bore the kids but walked around quite a bit and went to the Duomo, Ponte Vecchio etc. The weather was good on a couple of days but our 3rd day there was really wet so a brolly or mac would be very useful. It might be warmer and drier now.
We were extremely cautious when walking around especially with all the tales about pickpockets but I am happy to say that we had no trouble at all. The advice about using a money belt was great!
We ate at the Il Latini restaurant in Via Palchetti (I think) which was superb although the wait was long. But the service is wonderful and they serve you wine and cheese while you wait outside. Worth reserving but I noticed that even some of those who did had to wait for a while.
Took a half day tour to the Chianti region which was very enjoyable and we had a wine tasting session with snacks. We used CAF tours which is not far from SM Novella station.
Finally we stayed at a place called Soggiorno Gloria which is just a stone's throw from the railway station and good for those on a budget. We had a triple room with an attached bath for 70 Euro excl. breakfast.
Happy Travels for all going soon. Florence is simply amazing and this is one place where children are welcomed warmly. It is expensive with the exchange rate but worth it all the same.
