This is unsubstantiated by any links or documents, but I just wanted to share that the Herods Tel Aviv may be converted to a Hilton Doubletree in the near-mid future.
During a call with Hilton a few days ago to book a summer stay at Hilton Tel Aviv with certificates, I spoke with a very cordial and enthusiastic representative that had a daughter with a PhD in Holocaust studies with a concentration in the Holocaust in Ukraine and keen interest in Israel. We actually continued to chat quite a bit even after booking the stay.
At one point, she started to tell me about future plans for Hilton hotels in Israel as appeared in her system. She said a Doubletree was slated for 155 HaYarkon Street, which is the address of the Herods Tel Aviv hotel. She mentioned a couple of other new properties as well (a Hilton Garden in Ashdod and a Curio in Tel Aviv), but I was already aware of those two from press releases/news a while back.
I had not seen or heard any report about the Doubletree conversion, though. Here's hoping we have a new, reasonable cash/redemption option from Hilton in Israel - especially after the major Crowne Plaza losses!
