Time for management to take a closer look
Let me start by saying that this is one of my favorite resorts in the Valley, however lackluster service can be the weak link that erodes customer loyalty. I just left the resort about 30 mins ago and looking back at the past weekend, I was very disappointed in the level of service.
On Friday night (August 31st), there was no hot water in the villa, I called guest services and housekeeping repeatedly but no answer (this was approx 9:45pm). I then reported it to the front desk upon check out and the agent said "thanks for letting him know" (Really!)
Also in the villas (which are nicely decorated), there was a full kitchen but no pots/pans (this was a $40 upgrade)??? Several other villas (Marriott, Westin) provide complimentary pots & pans.
On Monday, the Lobby Grill completely messed up our breakfast order. I walked back to the room only to discover that several items were missing. When I called to inquire about the missing items, the staff member told me to come on back, which I did only to wait 22 more minutes to get what I initially ordered (and NO apologies from the staff).
When I checked out, my bill was incorrect and the front desk agent never apologized (he simply said he would fix it) and also never inquired about the stay - his main purpose seemed to be getting the guests checked out on time.
Again this is one of my favorite resorts - for business conferences & for leisure but for the first time I am seeing a decline in service levels compared to what used to be impeccable service across the board. 
Hopefully this is the exception and not the norm but I will be exploring other options the next time I plan a getaway or need conference rooms for a business meeting.
