Started with the PRICELINE link here... Bid 68, 72, 75, 78, 82, 85, 90, 95 using non-4* re-bid zones and no luck with 3/30/12 - 4/1/12. Didn't have to make it to Seattle Friday night so shortened my stay by one night and won the Sheraton first try with $90. My guess is it was the Friday that was busy and not the Saturday since I was successful with the latter bid. I called the Sheraton and valet parking is $44 while off-site self-parking is $30. Boyfriend is very protective of his car so I guess we'll be spending an arm and a leg for valet :(
