I'm looking at staying at a Marriot property for 2 nights. One issue I'm trying to deal with is parking. I know, for example, Sheraton Grand Seattle, charges $57 usd (!) per day day for onsite parking. I don't supposed there are public parking lots around that area that charges significantly less?

I guess it's a give and take. I would like to stay within walking distance to Pike Place but if there are better options (it's the parking that I'm worried about), let me know what you guys suggest in terms of a Marriot property.
