Queen Be, we found bus transportation at CBR to be excellent, with very short waits, but we were there at a low attendance time (early December). There are taxis available at the Custom House but not at individual villages. We had no problems making an 8 AM PS at MK, there were buses running, but I have heard, as you did, that they may have discontinued those early runs. I would think that a rental car would give you access to MK an hour before opening. If safetymom doesn't have an answer about the early bus runs, you might have more luck posting this on the transportation board.
