I am travelling with my Dad through Estonia (and popping across to St Petersberg), then down through Lativa, Lithuana, Poland then through Prague and Cesky Kromlov before staying in Austria. We do not want to be on a tour, but travel ourselves and have about 2 weeks to get to Austria. We will probably land in Helsinki (still being sorted) and make our way down through these countries. We will be independent travellers using local transport and staying in hotels along the way. We are fit but not interested in climbing mountains nor nightclubbing and will have a reasonable budget :).
My question(s) are - if you had 14 days what would the ideal itinerary look like? What form of transport would you take? What warnings would you offer? What is/are absolute must sees?
In advance, thank you.
