The private guide subject comes up often on this forum, so I just wanted to share this recent FB post from an american friend :
"Just came back from a wonderful 2 + weeks in france and israel. Had two incredible guides in israel, that in spite of my living there for 5 yrs was the greatest money ever spent!
It actually felt like a vacation which is amazing considering all the travels. "
FYI, they traveled with three young kids I don't know who they used either, but agree a good guide just adds exponentially to the experience.
