I'd recommend the Oly coast or Seattle. If you make it up to Seattle I'd recommend heading out to Browers in Fremont. They have a beer list that is spectacular at great prices. There are also more microbreweries in a two mile radius than you can visit in a day not to mention a micro-distillery and a chocolate factory.
Bringing your bike? Green mountain is a fun AM/xc ride with more elevation change than banner, plus a good Seattle view at the top. PM me if you're looking for someone to ride with- Me and a buddy have been meaning to get out there soon. Eat at the Tides in gig harbor- the halibut and chips is excellent!
Also downtown Tacoma is cool- indochine is good Thai.
I suggested green mountain because it's the closest worthwhile riding, but if you're willing to drive an hour to the cascades, the riding is even better.
Offer's still open to show you around a bit if our schedules line up- in fact I have a buddy living in GH that I ride with every weekend- would work well for carpooling. Might even have a bike to let you borrow if you need. We lean mostly towards AM/FR/DH trails that aren't flat
Beer and good trails are plentiful here in Washington, no need to suffer on a beach in Gig Harbor the whole time.
