It happened to me in February…I checked into a Hilton Hotel and they would not give me (a Diamond) an upgrade…said they were Full.
I wish I had thought to do this at the time:
Just accept the crummy room they offer, then go online from it and see what kind of rooms the hotel is selling. Complain to the desk clerk or online.
This should work for any hotel brand.
TripBAM.com is a website that will automatically notify you by email if the daily rate at your selected hotel (or group of hotels) drops.
This works even if you prefer to book directly with the hotel chain, in order to get full points-and-stays credit in their frequent-guest program.
TripBAM does this by checking the rates every day on the hotel’s website. Note that it does not work on AARP, AAA, government, etc. rates.
Utter the secret passphrase at check-in, and you will get a prize. Check MommyPoints blog for the secret.
