If you are looking for romantic, I would suggest the Royal Palms. It is right next to the Phoenician and very close to old town Scottsdale, but it has a much more intimate, casual elegance feel. It has the most "personality" of our nicer resorts, in my opinion. The Camelback Inn (also a JW Marriott) is very nice. The Westin Kierland is good if you are really focused on shopping and night life. The Fairmont Princess is also lovely. I used to be a wedding florist, so I have seen inside most of the local resorts. Feel free to PM me when you have your choices narrowed down and I can give you more detailed info, if you like :)
