After trying both, I'd say stick with Dunkin'. If there was one Tableau, Terrace Point or Jardin, I'd be happy to go multiple times, but the choices are Dunkin' and room service. As some of the other reviews mention, there are no good options for breakfast. This is most evident in the restaurant selection.
It feels like it was built to be a destination, but never ended up getting there, and now relies on local traffic to fill the gap. However, unlike its Las Vegas counterparts, it's just not somewhere I felt like I could spend 3-4 days and never leave. The rooms, the spa, the gym- all top notch.
