I never paid cash for the Park Hyatt as all my stays have been free. It is rather nice although the standard rooms are overpriced in my opinion. The suites however are top notch. If you're Diamond you'll be well looked after....if not I would look elsewhere for value.
I have stayed in the Novotel and I have to say it is a very good value priced hotel. It has a nice garden with pool and decent restaurant in the back. Rooms a bit small but very adequate and good at the price.
