R.v. Parking close to Pikes Place Fish Market??

The perspective of a lifelong resident: do not drive your RV anywhere near downtown Seattle. Even without all of the major road and construction projects going on there it is a mess. Park your RV, rent a small car, go see the Space Needle and Pikes Street Market, and then get out. Use your RV and your time to visit the many beautiful places away from the congestion that the State of Washington has to offer.
