Trafalgar has been around for years! Back in the day when I was in the travel biz....over 25 yrs....and they had a fine reputation then. So, if that's any consolation. I'd use them if they had what I wanted.
Personally, I like a tour that keeps you in a hotel and with doing day trips. Nothing as unsettling as packing and moving every other day. This all takes a toll on you.
