Hi,
Travelling to Europe in December/Jan and will finish the trip in Italy. I have tickets booked from Rome back to Sydney for the 12th Jan. Before that, I have 12 nights in Italy. Since I'm coming from Switzerland I think it would make the most sense if I started the trip in Milan. Florence is also going to be an essential part of the trip.
Now, I also really want to go Sorrento/Naples but I would have to go from Rome and then back to Rome (for my return flight) so I don't know if that's unreasonable. The alternate plan would be to visit Venice/Verona/Bologna before heading to Florence/Rome but I would say I'm not as interested.
TLDR; Is Sorrento/Naples unreasonable to fit in given Milan and Rome are the essential beginning and end destinations + visiting Florence + I only have 12 nights
Thank you.
