Our corporate rate at the Marriott *used* to include complimentary parking, but that clause was lost during a recent renegotation.
Other comments:
Haven't stayed there for a year+, but the rooms I had at the time were tired looking. Went to the formal restaurant on two separate occasions but both times I stood there and no one helped me. And one of the those times the bar/restaurant downstairs was out of the 3 things I was interested in.
Luckily I don't mind walking -- because I've always walked down to the Market from there. Sometimes 2x / evening. Even in winter.
But it is our designated property in Ottawa (along with the Holiday Inn in Kanata) so I'll continue to stay there to be a good corporate citizen, and enjoy the points & status from staying within the Marriott family (vs. the HI).
