It certainly can be done on your own. As Rick hints in his Israel/Palestine video, try to carve out some time to learn the Palestinian side of the Israel/Palestine conflict. Once you understand a bit more the extent of the occupation and conflict (i.e. West Bank areas that don't receive water 24/7, etc.), the more interesting and often uninformed, the American perspective of Israel is and you begin to understand a bit more why the U.N. has so many resolutions against Israel. We experienced first hand road blockage for a Palestinian road from Ramallah for no apparent reason, so it's good to get educated so you can fully understand both sides. I recommend Green Olive tours, however, some say they are too Palestinian-oriented, although we've taken 3 separate tours with them and found the guides highly educated and balanced (Yohav (Israeli) is particularly articulate and educated if you can get him). You can even visit a refugee camp. Green Olive is owned by an Israeli-Jew, who believes in Palestinian rights and his partners are both Israeli and Palestinian---which gives a very good perspective. If you are interesting in understanding a bit more before you leave, recommend reading The General's Son by Miko Peled. He is the son of an IDF General who became a peace activist. Visiting Hebron is particularly eye-opening (see Tomb of the Patriarchs). Consider doing the trip yourself, but picking up a couple of day tours to gain valuable insights that you might not fully get on your own. We went to Israel in 2016 and didn't expect to ever return, but return we did in 2018 and I now read Al Jazeera and Al Monitor news almost daily!
