I also will be going to London in two months. I am staying at the REN Chancery Court, a category 7 that has a room rate @500$. That only cost me 150K points. But, I got a travel package for 270K points even though I purchased my airfare. Why? Because I could convert 120K MR points for airline points on a 1 for 1 basis. Normally, you get 50K in airline miles for 125K in MR points. Lesson: If you have the points built up, ALWAYS do a travel package whether you use it all or not. There is NO requirement to use the miles for the same trip. The reverse is also true; you could buy a travel package to get miles for use on a trip A and book a future 7 night stay in a location for trip B.
