Thank you very much for posting this review as I'm planning on doing the same!! I have four award nights booked at the hotel in July as part of our Paris/Cannes/Nice vacation. Was debating between the Radisson or the Hilton AdT (at which I also still have a reward reservation at). Was leaning towards the Radisson due to the location and the smaller size of the hotel as compared to the Hilton. Location looked much better and more centrally located and with only 46 rooms I would get a more boutique feel at the Radisson vs the 400+ rooms at the Hilton. I think your review helped in the decision process and I will probably cancel the Hilton.

A couple of questions if you don't mind:
1. What Club Carlson level are you? Asking because of the upgrade you received. I'm currently Silver but have put in a request for a status match to my Priority Club Platinum Ambassador status.
2. Did you dine at the hotel or anyplace good near the hotel?
