Parking at the hotel is expensive - about $40/day to valet your car. However, there are plenty of public parking garages within a couple blocks of the hotel. We dropped our bags at the hotel, and went to lunch at a seafood restaurant in the Fillmore district. We came back a couple hours later and checked in at 2pm. Check-in time is normally 4pm, but they had a room available for us.
The hotel is very nice! Here's pictures of the lobby, fitness room, and rec room (with free arcade games and billiards). There's also a nice media center (where I'm writing this post), with a couple free computers, DVDs for check-out, books left behind by other guests (thank you for the worn copy of "Treasure Mountain" by Louis L'Amour), and TV.
