For OH and myself, often with sil and bil- we much prefer to see less to see more. Meaning that we always choose to cover less miles and less ground- to have time to look at one area really well- rather than rush, seeing just 1 or 2 sights per location, and rush off somewhere else. last year we did NE and N Sicily, and this year SE and the South- in 2 weeks each.
When we were in the USA last time, we kept meeting people on tours of 2 or 3 weeks covering the whole of the US- we limited oursleves to North Arizona, Southern Utah and central Colorado- and took 3 weeks to visit all the important sights at leisure, and behind the scenes too. Trying to do too much in too little time and not get a real feel for a place seems a real waste to us, personally. What about you?
