I bid on SeaTac airport hotels frequently. The general price range I get is $40 - $50/night for 3* hotels (Doubletree, Hilton, Hoilday Inn, Marriott) in the immediate SeaTac area (i.e., within 4 or 5 blocks of SeaTac.) Hotels in Renton and Kent will be MUCH farther away, I wouldn't put them in the airport hotel caregory at all. As was mentioned earlier, rush hour traffic may be an issue depending on the time of your flight. If you're planning to leave your car at the hotel, the Renton and Kent hotels may not not have an airport shuttle. In addition, it's been my experience that airport hotels in the immediate SeaTac area do not offer free parking, especially on Priceline rates. You can get discount coupons online (do the Google search recommended above), but expect to pay $9 - $12/day for parking near the airport. I think it's going to be a trade-off for you, close to the airport and pay for secure parking, or farther away and find free unsecure parking but possibly no shuttle so you'll have to take a cab to the airport. Finally, bidding in February and March on a hotel you're going to stay at in June is not a particularly good strategy. You'll have much better luck if you wait to within 30 days of your trip. Have you checked Hotwire to get an idea of prices that might be available? Do you have a back-up in case Priceline doesn't come through for you? There's a Holiday Inn Express near SeaTac that has a shuttle and usually has pretty good rates. Good Luck.
