Euro Trip! Need Reply!

Ok balls, Josh and I were looking at air ticket prices within Europe and quite ex so we need to plan now for Euro Ball Trip.

So the provisional plan is this:

Full Ball Strength Euro Trip
Up to 27 Dec: Stay in London at Koopad
27 Dec: Fly to Paris
From Paris we will use the Eurail Pass (http://www.eurail.com/eurail-france-italy-pass?currency=eur)

Josh has to leave on 7 Jan so we basically have 11 days for our full strength ball trip.
Itinerary is Paris - City in Southeastern France - City in Central Italy.

We need your input to decide on which cities to visit, for how long and whether you want to attempt a 4th city.
Southeastern France (http://wikitravel.org/en/Southeastern_France) - Marseille, Aix-en-Provence, Nice, Cannes. Pick one
Central Italy - Florence, Pisa, Rome. Pick one.
My pick is Paris - Aix-en-Provence - Florence and maybe Rome

So let us know your preference. Also, after the full strength ball trip, we can charlie mike to Spain, Czech Republic and so on.

To Do List:
Book ticket to London
Book ticket from London to Paris
Buy Eurail Pass
Pick destinations in France/Italy and indicate how much time you want to spend there.
Let us know your travel plans so we can plan stuff to do before/after
