Thinking about taking my girl to London (her first time) over valentines day and for you lucky enough to travel there frequently on business, wondering what your favorite Marriott property is.

Although I'd rather not spend the points required for a Cat 18 or 20 (just kidding, although it bothers me that London and Paris always seem to be so darn expensive), but it's only for 5 nights, so what the heck?

Marriott Park Lane? JW Grosvenor House? St Pancreas Renaissance? Something else?

Would like a nice property at a good location, so I'm prepared to step up and spend for a ridiculous Cat 8/9. Any of these known to offer Plats particular good service & nice lounges for breakfast (and maybe evening snacks if we're tired and back to the hotel in time)?

Thanks,
