There is a direct train from the FCO airport at 11:08AM and 3:08 [the later one arriving at 7:23]. That may sound like a lot, but you get on and off relaxing along the way. The journey is only 42 minutes longer than one from downtown Rome.
Without flying into Venice, IMO spending all this travel time is really questionable. You could skip Venice, combine Sorrento with a town on the Amalfi coast, travel by ferry, then a ferry to Salerno and a train to Rome.
i heard there is much more to do in rome than venice so we were thinking of doing 5 days in rome and 1 in venice and end the trip with 3 days in sorrento to relax but i will consider the 2 days in venice, if i fly from venice to napoli then go to sorrento (no airport in sorrento) would i be saving time ? and would i find good deals on plane tickets in july ?
appreciate the advices thanks
It might interest you to know that with non stop flights on Air Canada, it is cheaper to fly open jaw, into Venice and out of Rome, then a round trip to Rome, and that's without the added train fares. Of course you might have cheaper multi-stop flights.
So you are suggesting 4 full days in Rome, 1 in Venice and 2 in Sorento  and 4 travel days and hotel changes.
Venice to Naples it is better not to take the train [5:08 at 7:25am] then to fly.
All will be crowded for you, lots of tourists. Remember that two nights equal one full day. I would NOT go to Venice for 1 day. It is spectacular city. I, too, would drop Sorrento. 3 nights Venice and the rest in Rome. And, if you can fly into Venice and out of Rome (someone said it is cheaper) then you save time. That would be the best of both worlds.
I already booked tbe flight tickets to rome on july 23 and leaving rome on august 3rd, i have 11 days and travelling will be around 2 days between all 3 destinations so that gives me 9 days, i would like to visit all 3 places since its my 1st time then decide which places i liked more to visit in the future if i can
ok here is what iam thinking: day 1: arrive to rome at 1pm
day 2: rome
day 4: rome
day 5: rome to venice, spend the rest of the day there
day 6: venice
day 7: venice to sorrento or positano
day 8: sorrento or positano (relax on the beach)
day 9: visit capri for day trip
day 10: sorrento or positano (relax)
day 11: back to rome and spend the rest of the day in rome
day 12: head to the airport in the morning
Iam thinking of going to positano instead of sorrento as we are looking for beaches, nice scenery to relax at the end of the trip
What do you guys think? Appreciate all your advices
I've advised you to stay in Rome only once. Landing at FCO, there is a train to Naples at 3:08 [or the next one a half hour later] with a change downtown arriving at 5:13. From there you can get a driver to your Sorrento hotel for €80.
However you want to stay in Rome first. For €48 you can get a taxi straight to your hotel. For €20 less you can take the Leonardo Express to the Termini Station, and go on from there [Naples where you are not going takes 70 minutes]. If the Tibertina station is closer to your hotel the fare is €16.
