Actually no, not everything will be closed in Rome on Easter Weekend, although you definitely will want advance tickets for the biggies that are. The Colosseum, Palatine and Forum, for instance, will be open as well as Galleria Borghese (yes, advance, timed-entry tickets will be mandatory for all). So check the websites of the attractions you wish to see for hours/closing days, or any staffing issues which could shorten hours or close an attraction with little notice?
That said, Courtney, welcome to the forum! We really do try not to pile on to new posters with overloaded itineraries but, well, we'd rather express concern than not when a new traveler has the potential for trouble. As you can see, there's quite a lot of concern about your plan...and for good reason! There's "see as much as possible" and "experience as much as possible". Two different animals, that, and packing, unpacking and moving around isn't the fun part.
Realistically, this is what you currently have given yourself to work with:
1 full day Venice; April 8th
1 full day "Tuscany"; April 11th
2 full days on the Amalfi Coast; April 13 and 14
3 full days Rome; April 16, 17 18
So of your 11 FULL days on the ground (8th -18th), you'll be spending quite a bit of time in transit on 4 of them.
Shorthand notes: 1 day isn't enough for Florence and Pisa, I'd skip Bologna, and (pretty sure you'll hate this), I would skip the Amalfi coast too. I'd add time to Venice, Florence and Rome, and especially Florence if you want to day-trip from there. Save the Amalfi Coast until you can give it the time it needs and deserves. Oh, and no, I definitely would not drive from Venice>Bologna>Florence, or from Florence>Naples>Amalfi Coast. If you keep the Amalfi in the plan, please don't fly from Naples to Rome; you'll get there MUCH faster by train.
But here's the deal: which locations to trim from the plan, and which to add time to, depends on YOUR interests; what YOU most want to do/see on this trip. LOL, "everything" isn't an answer 'cuz that's when you end up with an Italy-at-a-Dead-Run plan! It's also too early on the coast for beach time, if your daughter had visions of paddling about on the Amalfi.
So before throwing a bunch of itineraries at you that we consider more rich in experiences, what can you tell us about your family? What do all of you want to get out of this trip, minus "as much as possible"? 😉
