Israel is a paradise for the tourist.The country is compact ,hospitable and modern.The tourist has an infinite range of places to visit depending on their preferences.There are tours operated by reputable travel organizations that can pick you up at most hotel and take you on tours either in the city where you are staying or around the country.
Private tour guides generally cost more but can cater for specific needs.
I would suggest you contact El Al airlines and consider flying with them and staying in hotels and go on tours according to your needs.
If you are interested in religious needs there are specific Christian tours,some even providing tours to denominations.Jewish tours would provide more time in Jerusalem.the tunnels around the Wall and Hezekiah's tunnel as mentioned in the Bible are two examples .The New Jewish Qaurter with Burnt House and the Rebuilt Synagogues and of course the Wall are is a must.You need no be obliged to visit it at 2am like President Putin,yesterday,but it's open to anybody at all times.If you are intersted in Archeology
the new Davids' City digs and the renowned Hebrew Museum are a must.
Everyone should perhaps visit the 10 most visited places like Masada and Acre with it's superb Crusader Halls and tunnels.Haifa is beautiful.Tel Aviv's beach and night life is world class.
Check it out and decide what you prefer to experience.Depending on the time available and how much you wish to spend will determine what you can see and how.
Israel is remarkable.Get the best out of your holiday.you will probably want to come back again,soon.
Enjoy Israel!!
Don't listen to the anti-Israel folk,who have an axe to grind.Israel is much safer than most countries.
I have visited and lived in Israel and have never felt insecure.I cannot say the same for Engand,the USA and any Middle Eastern,most European or any African country.
