Jerusalem - Travel officials who handle the lucrative Tel Aviv route are already calling this holiday season one of the most successful in recent memory. Not only are all the major hotels here filled to capacity; thousands of apartments were rented to tourists who will be spending the holiday in Israel. The robust tourist season is even more surprising at a time of growing unrest in East Jerusalem and the West Bank. The officials say that Jerusalem remains the main destination and that many hotels upgraded their kosher offerings to cater to the American kosher tourists. The influx of tourists also spells good news for restaurants, tours, takeout and other related businesses.
