Pacific NW Swinger Vacation

My husband and I live in Portland, OR, and we're looking for a lifestyle vacation close by.

We're thinking an Alaskan cruise or a resort in Las Vegas, but the only thing we can find is the Luxury Lifestyle Vacation Cruise in Alaska and it's super expensive ($8000 for a couple is the cheapeast ticket).

Any ideas - Hedo II is our favorite place on the planet, so anything close to that would be great.

Thanks!
