Is there a shuttle between hotels and convention center

There is a loop that stops at many of the hotels but many are with in walking distance

I'm not sure. Everything is within walking distance. I suppose if there is something going on there might be.

Depends on the event and hotel.

Several hotels are within easy walking distance. The Hyatt, Doubletree, Hilton, Embassy Suites and Crown Plaza are across the street

Yes- so long as you let the driver know it's the convention center.

No

As long as there is a show going on
