I cancelled it for a Hilton Bankside stay with a very attractive cash rate (which of course triggers 14x on an Aspire). I've got an upcoming stay at Flemings Mayfair this spring where I will be putting a significant room charge from Ormer on the room, which poses a similar question of using a Hilton AMEX or a different card. I'm not keen to roll dice on getting 3x Hilton instead of 14x Hilton, more inclined to just play it safe for 3x on a card which gives Citi or Chase points. It's unfortunate that there don't seem to be data points on how whether SLH incidental charges credit as general spend or Hilton spend for bonus points.
