Sounds like you’re headed for some fun, there. If you can work it into your busy schedule, I’d of course love to buy you a Weizen
- What time of year is the weather best?
Depends. (I know, fabulous answer) - I’ve visited Greece in mid-April, and it was great. I’d hate to think about it being much warmer, though. OTOH, Northern Germany can be surprisingly cold well into May. Overall, I’d say May is a good bet for the destinations you’ve mentioned - early May for Southern Italy & Greece, then England,Iraeland, Germany etc. I think you’ll have a hard tiiem fitting Russia into your schedule, unless plan on spending a lot of your time on travel.
- How feasible is it to backpack to certain places? Is it safe?
Short version: No problem. Bigger cities have their share of pickpockets & such, but I wouldn’t worry. I’ve backpacked by rail more times than I can readily remember and never even been scared.
- Which places are worth seeing and which are a waste of time?
As Coldie says, name your interests - there’s a bit of everything. And what age are your kids, BTW ?
England: London is amazing, whatever your interests. I never pass up the opportunity to laud the Imperial War museum, which - despite the dramatic name - is about as sobering a military museum as you’ll ever see. Perhaps something for the kids ?
Greece: What missbunny said about Athens - except, I’d suggest taking some time for the National Museum as well. Then enjoy a ferry ride and experience Greece on the island of your choice. Part of the Greek experience is approaching an island and seeing the whitewashed harbour town next to the blue Med - sigh! I think I’d fly to Athens, were I you - I’ve tried ferry from Italy and narrow-gauge train to Athens, and I wouldn’t recommend it unless you really want to rough it.
Italy: Rome is a more or less a must. Apart from that, the excavations at Pompeji are amazing. And the lakes in Northern Italy are nice indeed.
Germany: Munich & Düsseldorf are both pretty and has lots of history to offer.
France: I find Paris fascinating - but you probably need to know a bit of the lingo if you wish to see anything outside of the classical tourist attractions. The historical bits are great, the Eiffel tower is a flop (go take a look, don’t waste your time climbing it). If you’re into arts, you know where to go, right ?
Suggestion: If you’re driving from Germany to France, the region of Alsace (or Elsass) is worth a detour. They’ve somehow managed to combine the best of German robustness with the best of Gallic elan, and it works. Lots of medieval history, some WWI history as well - recommended. The white wine is pretty good, too.
- What is the best transportation?
Where in Germany is your base ? If you have a car (and preferably a copilot), there could be plenty of destinations reachable without spending too much time getting there. The autobahns are pretty good, but it still takes time.
For the longer stretches, trains are nice and pretty fast. Night-time trains - though expensive - can be great time-savers and an experience in their own right.
Hmm, that wasn’t very helpful, was it ?
Anyway, have fun - and if you make it to Hamburg, letz me know, eh ?
