Just came back from the trip in June.
A-M-A-Z-I-N-G
I went with "Israel Outdoors!" age group 22-26. Met the most wonderful people whom I still keep in contact with and we actually all went out a few weeks ago!
If you have the time, go
If you don't have the time, make time.
I'm not a religious person in any way, and neither was the rest of my peers on the trips as everyone was reform. Some of us never went to synagauge, some went a few times a year, some held informal shabbats at home, some didn't even know was shabbat really entailed (me).
In the end, I learned a great deal and met wonderful people. We even had a chance to interact with israel soliders our age for a few days of the trip. It was great to have the chance to see Israel in a new light, not just what we see and hear on the 10 o'clock news.
And yes, I felt VERY safe...even at the golan heights or driving past areas that were previously attacked.
