Okay, I know I want it all here.

Planning to stay the night prior to an 8:00am International flight. Once on a Friday night leaving Saturday morning, and once on a Tuesday leaving Weds morning. I plan on using MR points for the rooms. Which Marriott family property is best for this type of arrangement and convenient to Terminal 5.

Also, has anyone used points and then paid for Long Term parking at the same property, similar to a Park and Fly rate which I don't see as an option when reserving using MR points? Can it be more economical and convenient then parking with Avistar. (I need 7 days of parking so I'm trying to avoid the airport lots.)

Has anyone used Avistar and then arranged for the hotel to pick them up or Avistar to shuttle to the airport hotel.

Thanks for your help.
