The Hilton Arc de Triomphe is no longer a Hilton as of December 4, 2012. I just received an e-mail from I Prefer stating that the Hilton Arc de Triomphe is now called “The Hotel Du Collectionneur Arc de Triomphe Paris”. It is part of the Preferred Hotel & Resort group. Here is I Prefer’s address for the hotel – http://www.iprefer.com/luxury-hotel/Paris/The-Hotel-Du-Collectionneur-Arc-de-Triomphe-Paris/
The review is still of this hotel, but obviously is no longer relevant as it pertains to Hilton Honors benefits.
You can read review of the hotel in the “prior posts” drop box – August. Or click on this link; http://patstravelreviews.com/?p=48
