Had a terrible experience. The property manager gave us the wrong door code -- so trying to check in at 10:00 pm while 25 degrees outside, we were locked out. After calling/texting/emailing the 24/7 customer support line for two hours, we relented and checked into a hotel. Family of six crammed into the only hotel room availabe in town resulted in no sleep for mom and dad, with a rough night for our four kids.
We heard back from the property manager at about 5:00 am the next day. They gave me the correct code and apologized. Unfortunately the night cost me an extra $400+ for the hotel (holiday week) and we lost the next day of skiing. The property manager offered no reimbursement, stating that they responded in a reasonable amount of time. This fail on their part was pretty legendary, followed up by an equally heroic effort to not correct the wrongdoing that they acknowledged.
Separately, the unit is really out of date and does not look like the pictures. Much darker than depicted, the beds are uncomfortable, you can hear the upstairs tenants' every move, and my favorite... no plates or bowls. Silverware and cups, but no plates or bowls. Classy.
This place sucks. I've been coming to Mammoth since I was 8, so 30 years of 2 to 4 trips per year, and I've never had a bad experience until now. Super bummed.
