Opps, what can I say? I was out with a tour group and missed this post.
Touring Israel is generally a very good thing for any Bible Believing person. Getting matched up with the right group and the right sort of tour, however, can be challenging. I would absolutely love it if this forum decided to put a tour together. I promise to be available to give professional advice on the itinerary, timing and prices. Here are a few general rules...
The larger the tour group, the less access each participant has to engage with the tour leader and the tour guide. That can work out just fine if the group has common goals and interests or if there is no strong central leader. My personal preference is a group of about 35. My last group was only 4 people though and it was superb. (I had two US Navy chaplains [Baptists] and two lay leaders [Roman Catholics]).
Nothing in Israel is inexpensive. Just plan on it being expensive. Plan a minimum of $10 per lunch per day with at least one lunch being $20+.
Start thinking early about what you want to see/visit. If you want to have a theme, that will play a role in the planning stage. Extra activities can enhance the tour.
Hearing more than one voice for devotionals and teaching will enhance the experience.
I'll add more later.
