Currently flying SIN-LHR and it's too late to change my reservation. Seeing this thread pop up and then all the negative comments -- which only seem to get worse and worse -- is quite depressing. Sounds like this property is operated like a lower end domestic US property. A good reminder to do research before blindly booking a hotel or thinking brand standards and market competition provide any assurance as to quality within the Marriott Bonvoy family anymore.
Oh well, annoying, but not the end of the world. I'll take breakfast in one of the *A lounges I guess.
