I did a search a saw a few related threads with some good info, but I also had a few specific questions:
1. How long is long enough? Is 3-4 weeks good enough to see lots of sights and visit lots of cities? Or is it THAT much better if you're able to do 2 or perhaps even 3 months?
2. How much planning should you do in advance? For shorter trips I normally I like to research quite a bit to maximize the time I have available, but for something like this (more of a relaxing, culture/sightseeing trip), should I just map out specific places of interest, and perhaps some rough travel timelines?
3. Any tips on when is the best time of year to go (i.e. low season, cheaper airfare, less busy, etc.)
Thanks
