I live in Seattle, so I can advise you: The Seattle scene is minimal. Only six clubs within the city limits. Three others in the surrounding suburbs. Six of those nine are Deja Vu clubs--moderate enjoyment level clubs. All nine clubs are juice bars, no actual tip rail in all but one club (and I wouldn't recommend that one). Nude dances on stage, but all lap dances are bikini. Some dancers are able to flash a little. You will hear of isolated, infrequent reports of great mileage, but that's on an individual dancer-by-dancer case. On a typical business trip, you're not likely to encounter a high mileage dancer. Just to see an interesting club, Dream Girls (downtown) is anther Deja Vu property. It's the newest club in the region. Parking may be scarce and expensive. The club is in the block next to Safeco Field and Qwest Field. If the Mariners or Sounders are playing home games while you want to go there, it could be difficult. I go the the Deja Vu, Lake Forest Park, mostly. It has a good selection of dancers. If you'll be closer to Tacoma, the Deja Vu, Lakewood is similar. (Are you getting the picture?)
It was much, much better in the old days, prior to June 2, 2008, when a major multiagency LE raid on a chain of four strip clubs lead to their 2010 closure. Subsequently, their owners plea bargained to felony money laundering and prostitution charges (i.e., too much high mileage).
