Well I enjoyed the SLUT, and stayed at the Marriott. Just across the road, very convenient. It was fairly inexpensive as we booked early - boat show was part of a family ski trip. I did notice very long queues for the shuttle bus back to the indoor section of the show towards the end of the day, so I would suggest visiting the afloat section early if your hotel is in that area.
Kudos to Phil for hospitality!
