Phew - that's busy. That said, on Day 1 I don't see any reason why you shouldn't do San Marco first [it gets very busy] and then the Medici chapels and san Lorenzo, with the Bargello if you have time.
on Day 3, you are dodging all over the place - santa Croce and santa maria novella are at the opposite extremes of the centre of the city. I would go to santa Croce if I were you - I stayed near here last year and it's a fascinating area, with a lovely market just north of Santa Croce itself. if you then cross the Arno by the bridge nearest to Santa Croce, that will bring you quite close to the Piazzale Michelangelo. From there, I would go to the giardini Bardini rather than the Bobili; the latter is really quite neglected and not very interesting IMHO, whereas car rentals in the philippines the Bardini I found to be lovely and full of interest;
Sadly the wonderful rose gardens car rentals in the philippines won't be open at that time [they open in the middle of May I believe] but it is still lovely walking car rentals in the philippines back down into Florence through Altrarno, and you could cross at the Ponte vecchio if you wanted to see it.
2 extra suggestions - after the accademia on day 1, you could consider getting the bus up to Fiesole from the piazza san marco [you'll be just round the corner] and having a meal or drink up there - the views over Florence are lovely.
also, in the piazza san marco, or rather on the corner of the square and via Cavour, there is a very nice cafe with very superior food, but the best thing about it is the waitresses uniforms - they are VERY smart.
Now I just have to work on Venice,Paris, and London. (doing quick stops in Pisa and Cinque Terre, but I not having an itinerary for those-since they will be such shorts stops). I have a feeling I need to cut down London and Paris by a lot, based on the responses I got from my Rome and Florence Itineraries
I hope that you are factoring some down time for R R - all those museums, car rentals in the philippines galleries car rentals in the philippines and churches can get very samey if you try to do too many, leading to cultural overload, so that in the end you don't remember what you saw where or even care very much.
Yeah we are taking 2 days in Cinque Terre to do nothing after (Rome,Florence,Venice), then after a week in Paris we are taking 4 days on the Normandy Coast doing slow travel, before heading to London.
There are some places, like Pisa, where I don't care that I am going to spend 4 hours in on my way through. However, to do that to every European city does not do any of them justice, it doesn't surprise car rentals in the philippines me that she enjoyed swimming and relaxing in Cinque Terre!
I Fratellini is just a sandwich stand. You eat standing in the street although there are racks on the wall to hold your wine glass while you eat. With all the touring, you might want a sit down meal instead.
When you're at Santa Croce, look for the line painted on the interior wall near the main door (facing the piazza) which indicates how high the 1966 flood waters rose. The crucifix by Cimabue now hanging above the main altar was plucked from the muddy waters, came to symbolize the city's recovery from the flood and only recently was re-installed after restoration that took decades. Don't miss the refectory next door to the basilica. Taddeo Gaddi's Last Supper and Tree of Life are on one interior wall. It's one of the earliest representations of the Last Supper scene after perspective was 'invented.'
