There is a Holiday Inn Downtown that does have a shuttle from the hotel to the ship the next morning. I've read very mixed reviews on this hotel. It's about half and half from being a great, clean place to stay to it's a dump!. I had a bunch of points from my travels so I used a few of them to book the hotel. I've stayed in a lot of Holiday Inns and usually you can depend on them being pretty good, not fancy or by any means the quality of a $200 a night hotel. I will post my results when I return Oct 4 from a cruise on the Splendor.
I'm not sure about the connecting rooms and suites but from what I understand the neighbor is a little iffy as far as walking at night. There is a hospital across the corner and church on the one corner. Their shuttle will take you anyplace within 3 miles.
Good luck!
