I will be traveling to Israel, arriving Wed. May 16. I had originally planned to rent an air B&B for the next 5 or 6 days, in Jerusalem, near the German Colony, then going to the Negev. I just realized that we will be in Jerusalem for both Shabbat AND Shavuot, affecting our touring plans. I'm hoping to "flip" my plans a bit, by staying in Tel Aviv on the 16th, then going to the Negev (Masada, Ein Gedi, Dead Sea, etc) on the 17th and 18th, returning to Jerusalem on Sunday, the 20th, in the late afternoon.
Will Masada and the other Negev sites be open on Shabbat and/or Shavuot. Anything else we should be aware of arriving in Jerusalem on Shavuot afternoon?
One more: Would you recommend a guided trip in the Negev, or renting a car and going it alone? I'm in my late 60s, and not in the best shape for hiking. Also, I lived in Israel for 2 years in the early 70s, and my Hebrew was pretty fluent, but it's very rusty. I'm hoping it'll come back a bit while we're there.
