We are going to London in May. I would like to use my Marriott or Hilton points for a one night stay at Heathrow Airport. Which hotel would you recommend? They are all about the same point price. Thank you for your responses!
Do they all take the same level of points? If so, your decision should be based on which terminal you are using. One hilton is AT terminal 4, one hilton is near but not at terminal 5, the Marriotts are convenient famous cruise lines in alaska for T-1, 2, 3.
I haven't stayed in either one but have been in lobbies/lounges both of both. Not a lot of difference quality-wise. 6 of 1/half dozen of the other really. At least in the bits I've seen. Nice airport/business hotels.
The Marriott Heathrow is a newer modern style hotel and was opened not that long ago, it's a striking building with lots of glass; the Marriott Renaissance has been there for years and was previously the Penta, more old fashioned exterior but good views of the runway, as it is on the opposite side of the road to the Renaissance (if you get a room on the runway side). It doesn't make much difference, but personally famous cruise lines in alaska I would take the Marriott Heathrow.

alan I don't know about OP, but I usually stay at a Heathrow hotel because I can never make it back from France, Spain, Italy, etc. in time for my Virgin flight to SF. There is only one flight a day; and I fly Virgin as I have mega miles that permit me to fly Upper Class.
