Bringing my post over from another board here on the DIS as a heads up to be aware. Make sure your car is parked:
Last week, I decided to splurge and surprise my family with a Poly stay. We drove up about 10:30 pm. There was a family ahead of us who got out of their car, gave the keys to the valet, and went inside. We sat and waited about 20 minutes and no one from either bell services or the valet came to see if we needed help. Finally, my daughter got out of the car and began unloading luggage. I had to go to the bell service desk and ask for help. There were 5 cast members standing around talking. The bell service guy loaded our luggage and I gave him the keys to my car. He said to leave it running. We went to our room. After the kids settled about an 1.5 hours later, my daughter and her wife went to walk around the resort. They walked back to the main entrance where they saw my car was still running, had the windows down, and the keys were on the console! It had been storming. Thank goodness, the interior of my car did not get water. She spoke to the valet who ranted and said no one told him the car needed to be parked. Then, he made the comment that valet cast members had lost 4 sets of keys during the past week!
DD and DIL came back to the room and told me what had happened. When we woke up, I went to check out after barely sleeping and happily, the cast member gave me zero problems. We went to the MK. While at the Crystal Palace, a manager, Tony, called. He was very professional and apologized profusely. He offered incentives for us to return. I told him that I really appreciated his offers but I just would not feel comfortable at the Poly after our experience. Anyone could have walked up and driven away in my car.
BTW, the monorail access at the resorts is nice but with all of the people visiting for meals, long waits are not unusual. It really is not all that it is cracked up to be. I definitely would not let this be the deciding factor on a resort stay. If you plan to spend a lot of time at the MK, book either the CR or BLT. It's an easy walk from these to the MK.
