Am I able to make Skype calls to USA from this hotel? If yes, What are the charges?
The WIFI in Israel hotels is usually free of charge and there is no exception in this case.
Unless you need a wide band for working issues (e.g. working from home in the computers/networking field) then there's no problem.
Once there is Wifi you can make skype calls
There was no charge for WIFI in the hotel. I presume that tis means that SKYPE calls are also free.
Wifi is found in every hotel in Israel, the David is no exception.
However, it is not always free (especially in this area).
You'd better ask the hotel directly for the charges.
