ok...had a lengthy chat with a very nice woman at the palazzo who had just done some training regarding Amb and RA benefits. She read these benefits to me directly from some internal source (Although she had to refer to her manager a few times to confirm some questions)

The benefits for an RA are (as confirmed by palazzo)

* Guaranteed room upgrade - They will upgrade from a standard 720 suite to either the 900 ft fortuna or the 1300ft sienna...whichever is available. Upgrades will NOT be to Prestige level. There is a $100 supplement (can be more dependant on what room type) for Prestige level.

* VIP Check In

* 8am Check In

* 4pm late checkout (Apparently this is not guaranteed but on availability. She checked this with the manager and he confirmed it was on availability although she did go on to say that this shouldn't be a problem and they will honour it pretty much every time)

* Fresh fruit on arrival

* 24 hour room guarantee

* Complimentary minibar

* Complimentary in room internet

* Complimentary movie

* In room welcome letter from the GM

* Complimentary newspaper

* Comp access to the Canyon Spa Ranch

* Free local phone calls

All in all pretty much everything you would expect but sadly no Prestige lounge access.
