I have just stayed there - almost seems as though it was built as an Embassy Suites [atrium style] but branded as a Hilton Suites - maybe for families for Disneyland.
Rooms are a good size - had a regular room and then returned to a corner room.
There are easels with swatch samples of the new color palette for all fittings and furnishings. A great receptionist told me that most staff [many since opening] know that it needs a refresh and are excited about the potential positive vibe of change.
Floors 8,9,10 are HHonors / Executive floors [Gold and Diamonds] which incudes the drinks and breakfast. I had three breakfasts and they were the least tasty of all my stays. I have just completed a US trip with 21 properties, and many Hampton Inns had better quality breakfasts.
The ART shuttle worked very well [$5/person] and one can use the whole system all day if necessary [as far as Knottsberry Farm].
It is an easy walk to the Orange/Anaheim Premium Outlets [the Doubletree is on the outlet block]. I also walked to the Anaheim Amtrak station to go to San Diego for the weekend [yes, Australians walk a bit]!!
I think it will be a good fit for the Embassy Suites brand.
