Each night look at your next day's agenda and find scriptures to read that took place in those locations. Spending time studying and pondering the scriptures is key to inviting the Spirit.
Before you go next time in a year, spend time reading all of the gospels looking for mention of places and look them up so you know where they are. Make a list of scripture passages per location.
Enjoy your trip.
Also note that although Israel is a great place to visit, if you want a spiritual place go visit a temple.
