Hit me with it ladies and gentlefellows.
Been to both a few times - waddaya want to know? Are you getting the train down or flying to Sicily?
Rome- If you are interested in the Vatican museum book your tickets in advance, otherwise you will be queuing for hours.
Sicily - Taormina is beautiful, but accommodation is expensive there.
I loved Mt Etna, well worth the trek up.
I also loved Corleone and Plazzo Adriano (where Cinema Paradiso was filmed)
There is a big price difference between Rome and other parts of Italy, inc Sicily. Expect to pay closer to Irish prices in Rome, unless you go off the beaten track.
I hear renting a car is a must in Sicily. The food is meant to be sensational.
True Mattie but in Rome you find a lot of places with "tourist menus" which consist of two courses with wine or beer and are quite reasonable.
Sicily is quite a rip-off imo. Min. €40 from the airport to anywhere. "Taking the tourist's dollar" is quite popular in bars and restaurants there also.
I stayed in Catania and visited the places you mentioned. Excellent trips.
You need to hire a car in Sicily but the inter-city buses aren't too bad.
I'd go back to Rome but not to Sicily tbh.
