Terrible Check-In Pretty Much Ruined Trip
We are frequent travelers and up until last year were Hilton Diamond members. We have recently stayed at some of the finest resorts in the Phoenix/Scottsdale area: Four Seasons, Royal Palms, Westin Kierland Villas, and Princess. We were expecting the service at the Arizona Biltmore to be on the same level as these resorts. It most definitely was not. 
Upon arrival, we valet parked our car. More on that later :( 
At check in, I inquired about upgrading our room. The woman at the front desk was completely clueless. My husband and I got the impression that she had never worked a front desk before and this was her first day working in the hotel industry. This is a WALDORF property! After about 15 minutes of her not understanding what I was asking for and my husband ready to completely lose his cool, I finally requested she find a manager. He was accommodating and found us an Ocatilla room, which we paid more money for. I don't understand how the resort's first foot forward could be someone so poorly trained and clueless. I talked my husband off the cliff and we headed to the room ready to put the past 30 minutes out of our mind and enjoy our vacation. 
Not so fast. We had asked the valet to get all of the bags out of the trunk and requested they be brought to the room. When they arrived, one of our bags was missing! Our bags had been sitting on a luggage cart the entire time we were hassling with the front desk and we were sent into panic mode as to where the bag could be. Murphy's law, it was the one bag that we absolutely could not lose. Eventually they found the bag (claimed it had never been taken out of the trunk) but WOW what a TERRIBLE start to this vacation! 
The rest of the stay was just okay. We got massages and facials in the spa and my husband said it was the worst massage he's ever had. Mine was pretty good. Our upgraded room in the Ocatilla section was about as far away from the main entrance as it could be and was a good 10 minutes walk. We're young and in good shape and it was a haul. 
I really can't see wanting to stay here ever again.
