The places I would like to see are probably more expensive like London for example.
I’ve been to Europe twice-—France and Italy-—and did not find it inexpensive. I’ve learned a lot watching programs like Rick Steve’s Europe and would probably borrow a lot his ideas including staying in bnbs. My wife however, does not like “roughing it.”
I’m a WWII buff and would like to visit Russia and see Stalingrad. I’ve only read about 20 books on that battle alone.
Same principles work in Europe.
Just saying.
