You will need to book a flight to Tel Aviv Airport. From there, your best choice will be to take a train to Jerusalem Yitzhak Navon station. Trains depart every 30 minutes and it is just a 25 minutes train ride. From there, you can either walk one kilometer, or take the light rail in the direction of Mount Herzel and get off at Kiryat Moshe. From there, it will be just a 300m walk to your hotel.
Alternatively, you can also take a taxi from the airport to your hotel, it should cost you 300-350 ILS. Be aware that between Friday and Saturday evening there will be no public transport at all, so in this case you will have to take a taxi.
The hotel is very close to university's Givat Ram Campus where the conference will take place, So you can simply walk. Alternatively, you can also take bus 42 or 68 from Government Complex/Lorch to Music Academy High School.
We will arrange transport from Jerusalem to Ein Bokek for all participants of the conference. There are also buses 444 and 486 from Jerusalem Central Bus Station to Ein Bokek.
