The thing I love/hate about Marriott is it's consistancy. You always know what you will get with a Marriott, you are never suprised. I can honestly say I have never been disappointed at a Marriott and I have never been overly impressed either...except the Ledra Marriott in Athens and that's in comparison to all other hotels in Athens.

Hilton's IMHO can be much better and much worse...they don't seem to have a set standard for their hotels.
