Honestly I would get a hotel through priceline and then just pay for parking at the airport (coupon on the website).
My experience is that hotels usually only have 1 bus and if they are busy or you just miss it you will be waiting. Last March we waited 45 minutes and we then ended up taking a taxi.
The airport parking shuttles, I have only waited about 5 minutes and they take you right to your car, so you are on the road much faster.
Sorry I missed the part about not needing parking. In that case any of the airport hotels are ok in the morning, the issue always seems to be the pick up at the aiport. We stayed at the Hilton Garden Inn and it was nice.
