I am a lifetime Platinum member. Within 6 hours of the announcement of the wedding date for the Royal wedding in London I tried to book any of the 5 main Marriott Hotels in central London and none would even accept a reservation cash or points! Why? Is it typical to block off entire hotels for large events? No access even for Platinum members? 24 hous before the wedding day announcement not a single Marriott was listed as sold out!
