Had a weekend stay for a special occasion - and have mixed feelings. It's a nice property overall, especially for a "free" stay using a certificate. Just as the poster above, upgraded to a corner room (or offered a paid upgrade to a premium Gold Coast Suite at $500/night). The corner room layout is somewhat odd with a long and narrow hallway that is blocked by closet doors when trying to get things in/out. Our room also had a weird unusable "balcony/facade detail" blocking some of the view, and very poor soundproofing - could hear everything happening in the room next door or in the hallway.
New room design is ok, but is more reminiscent of an Andaz than a Park Hyatt. Some closet drawers were already coming loose. Nice bedding, but towels were a bit scratchy... and don't get me started on "institutional" toilet paper. Only one robe in the room, which was odd. Breakfast credit was the same as mentioned above - $50/adult, and can be used for room service, except for the delivery fee and (auto) tip. It cannot be used for Sunday brunch, and actual breakfast service is only until 10 am on Sundays, so no sleeping in late, and no more sushi for breakfast.
Service was nice, but not really screaming "luxury hotel" - and there's absolutely no "above and beyond" here. Oh, and they no longer have a house car. If not needing Hyatt nights or burning certificates, there are much better luxury hotels in the city, unfortunately.
