BE NICE!
There are only 3 hotels.
The meridean is the best for its point value. However. poor service and rooms need updating (still a 5 star hotel for israel).
Tel aviv has great service and very nice rooms but not as "resort style" as dead sea or eilat.
Eilat is nice, rooms are suites, service is pretty good.
Hard (almost impossible) to get cash and points in eilat and tel aviv.
