My wife and I booked a 1 night cruise on the Crown Princess leaving from pier 91 in Seattle, just blocks from our house, to Vancouver BC. We were celebrating our second anniversary and the price for a suite on this repositioning cruise was too good to pass up. For those unfamiliar, when the cruise lines move ships between destinations they have a series of less traditional itineraries that are often shorter than your standard cruise. For the Alaska market this typically means there are a number of 1-night cruises from Vancouver to Seattle in April/ May and the other direction in September and early October. It's also typically possible to find inexpensive ground transportation for the other direction (Bolt Bus or Amtrak). You can live lavishly for a night, eat constantly for the 20 hours you're on the boat and enjoy everything else the cruising life has to offer.
