Navajo National Monument

We used to like this hotel and it was always on our first choice on the list but not anymore after our stay this time. We arrived at the hotel and because we had a full size van, we were not able to go through self parking area so we had to do a valet parking. We were told that there will be a one time charge for $150 plus $40 per day, then $40 per day after that. We stayed 2 nights so total $230 for parking. Then, it's shown as tip for the $150 on the receipt. We understand that we needed to tips but $150 for 2 nights parking? That's crazy. Additionally, why does it show as tip instead of one-time charge? We feel ripped off and really disappointed. What kind of customer service is that?
