It’s a bit early to reserve trains indeed. Three months in advance I’lld say, sometimes a bit later (France, Italy, Spain can be a bit later).
Eurostar London-continent should be reservable already. Best place to get it is on www.raileurope.com (also for French and Italian train reservations). Make sure to add your Interrail pass in the discount.
Sicily can be done by train (which then goes on the ferry), thus already included in your fare ;)
Half June there’s a minor timetable change, so looking for trains later than that date probably won’t prompt a response.
Planning wise, a lot to go to between the UK and Sicily. Half of Europe awaits. I’lld say, take a map, look a bit around where you’lld like to go, and use www.bahn.com to plan your itinerary a bit (almost every train timetable in Europe is included).
→ Don’t find any timetables? Choose a random date next week, offer will be the same in 6 months, or only have minor changes. Then you’ll get an indication about travel times, and amount of connections per day.
Eurostar can currently be booked until 17 May. When they will open reservations from 18 May is anyone's guess.
Thank you for your feedback.
Had a couple of days looking at what to do and where to go. Looking like this at the moment.
Leave England and travel to Paris - 2 days.
Paris - Milan - 2 days there (4 days trip total)
Milan - Verona - 2 days there (6 days trip total)
Verona - Florence - 3 days there (9 days trip total)
Florence - Amalfi Coast - 3 days there (12 days trip total)
Amalfi Coast - Sicily - 7 days there (19 days trip total)
Sicily - Matera - 1 day there (20 days trip total)
Matera - Paris - then home days 21 onwards.
From anyone's experience, is the duration in each "hub" ok, or would you shave a bit of time off and or add on anywhere?
From Florence I was thinking a day trip to Tuscany, Sue a or Pisa
From the coast trips to Capri, Sorrento and Pompeii
Once again, thanks in advance.
