Kevin,
Thanks for the additional information.
Another question.... is there any way you could add at least one day to the Italy portion of your trip, and one less in the U.K.? As flights are not yet arranged, that may be possible? With your present plans, you only have about three days to cover both the Cinque Terre and Tuscany, and (IMO) that will be a bit challenging (albeit not impossible).
Flixbus is certainly one option for getting around, but most of us here prefer the frequent and inexpensive trains.
If you want to maintain your original plan, this is one option you could consider....
- May 12 - arrive Genoa port - take Taxi to Genova Piazza Principe station and train to Firenze Santa Maria Novella station - given your arrival time of "midday", you may be able to connect with a departure at 13:47, arriving Florence at 18:07 (time 4H:20M, one change at La Spezia Centrale, second segment via Regionale so you must validate ticket prior to boarding train) - dinner and light touring in Florence.
- May 13 - take day tour of "Tuscany Country Villages" with local tour company, or take day trip on your own. I believe there are some tour companies listed in the Rick Steves Italy guidebook.
- May 14 - spend morning touring Florence - depart afternoon for Monterosso - you could consider a departure at 13:53, arriving Monterosso at 16:53 (time 3H:00M, one change at La Spezia Centrale, first segment via Regionale so ticket must be validated before boarding on the day of travel) - I'd suggest booking accommodations as soon as you have your Itinerary finalized as that area books up quickly at that time of year!
- May 15 - tour five Cinque Terre towns using the local trains or combination of train / ferry (depending on weather).
- May 16 - take train to Pisa Airport - one possibility is a train departing at 12:42, arriving Pisa Airport at 14:18 (time 1H:36M, 2 changes at La Spezia Centrale and Pisa Centrale) - Flight to London - one option is easyJet which offers flights to both London Luton and London Gatwick - at the moment, Luton flights are much cheaper - flights to Luton depart at 16:20 - if you decide to book with easyJet, be sure to read their terms and conditions carefully, especially related to luggage limits - those who book earliest get the best prices, but the cheapest tickets are non-refundable and non changeable so choose carefully.
There are of course numerous possibilities, and this is only one suggestion.
You can check guidebooks for hotel suggestions in Florence. I normally prefer hotels that are reasonably close to the rail station.
For hotels in Monterosso, you can choose between staying in the "old town" or the "new town" (both sides are easily walkable). If you need suggestions, post another note here. If you prefer to be closer to the rail station, it's in the "new town". I'd suggest spending at least one evening in the Cinque Terre, as the place can be mobbed by cruise ship passengers and bus tours in the day time. Having the quieter atmosphere in the evening allows for a much nicer visit there.
Good luck with your planning!
