As an SPG loyalist I've often complained, both on this forum and others, about the poor implementation of "Senior" rates at Starwood properties. So, for the last few months I have not even tried to use Senior as a search term when looking for a rate. I was browsing some old threads and came across erc reminding us that Marriott has a meaningful "Senior Rate". So, as I was booking a couple of nights in London at the Heathrow properties for use en route to the Wales - Italy rugby international in March, I thought I would try searching for a senior rate. Imagine my surprise when I was offered a rate £10 per night lower than the lowest prepaid rate. Not only that, but the Senior Rate is flexible. So I have 2 nights at the Sheraton Heathrow for 2 for the inclusive total of £121.30. Not sure if the sudden availability of senior rates is anything to do with the merger, but either way, its made me happy.
