The last thing I will say on this whole topic (other than letting you know how Marriott and Amex deal with it) is I bet many people who stay at this hotel never notice the $1100 charge. Figure average income there is probably between 2 and 5 million depending on the week. Many of these guests bring families. They may run up $15-50,000 in charges in 7-10 days in Aspen between food, booze, other lol, Lift tickets, skis, flights *(some private), private lessons, champagne, club fees, limos, helicopters, etc. Im not in this spending range but I likely wouldn't have noticed the charge till I did some reimbursements for work in 3-6 months and frankly at that point might have thought it was a legit incidental from an expensive resort. We only noticed it to dispute it because it put my friends card over the limit and she got a notice on her phone.
I bet many people book a trip to Aspen in points. Many arrive late (Flexible schedules, biz meeting changes, net jets, etc) Many business men travel and likely check into hotels late all the time and had no idea what a no show was like me. About 30% of planes into Aspen cancel or are badly delayed - winter mountain weather. I don't know this but I bet this $1100 fee add on is great business for the h0tel. Why they were so Adamant not to reverse it (I thought for sure they would reverse it and say now you know for next time). I bet there are a lot of these fees out there at this hotel and I bet many clients never notice the fee at all thinking they just checked into their hotel a day late and all was normal like I thought till we got the text, That;'s probably the biggest way to hit this hotel is start publishing about this fee or advertising it nearby in town. I bet its big business.
