Yesterday denied later than 1pcheckout at BWI Springhill Suites. Told they were fully booked. Asked to extend stay one night. Told again fully booked. Asked again at noon. Told fully booked no later checkout. Seconds later called from front desk said could do in King, no two queen rooms available, I said no thank you. Immediately went to Marriott website, three two queens available. Checked out at front desk. Told agent about late check out, said there were ions avaiable. Was very polite. At this point she turns her back to me passing me along to another agent as she chooses to answer phone instead of following through with me. I leave saying I would call Marriott. I did so, Rewards agent was very careful to hear me out. Her excuse was that reapservations and cancellations happen. I said it was statistically highly unlikely that in moments after front desk agent said they were full that I would be able to book three rooms on website. rewards agent offered 30,000 goodwill points, I said thank you. Then check this morning and only 3,000 "good will" points were posted. I emailed them about this. Wonder what they will ask? Today I have cancelled upcoming 8 night reservations. Will probably not return. Most upsetting is not the loss of a couple of hours in the room, although that would have been very helpful for my business day, was the apparent untruths (is that the polite way of saying it) told by this property's front desk staff. Would love to know why. Was I incorrect in my understanding, do not think so. But I do not like to complain, especially about workers, who generally do excellent work.
