Take the RESORT boat (smaller boat)-stay to the right side of the dock. We think its faster than the MK boat. The Resort boat will take you to CR and you can catch the monorail there.
The monorail is on 2 "tracks" one that goes directly to the TTC -(this will also take you to another "track" to EPCOT-you must change monorails) and MK. The other "track" all three resorts-PR, GFR, CR) and TTC.
