With many stays, I really enjoy learning about great properties that were so memorable to people. In my case, it was not just location or cost but the experience that was so special.
I know I have read about the Ren. Ch. Court in London, (I haven't been), but here are a few for my vote:
San Diego Marriott Marina
Seattle Marriott Wharf
Monte Carlo Ren, Cap d'Al
Paris Marriott CE
Have any to share?
India - JW Marriott Mumbai (see my other post on this for detail - fave Marriott hotel in the world),
So Cal - Marriott Del Mar - wonderful outside dining/sushi bar
Phoenix - Renaissance Glendale Resort & Spa - amazing king suites
