I think you'll be fine. I fly over for the day and had read and re-read all the warnings etc... of course I had a guide since it was just a day trip so I felt a little easier about that. There were only two of us on the "tour" and on the way back to Flores we came upon a van that had broken down. A couple flagged us down and you could tell the driver and the guide were on their toes. The couple wanted/needed a ride into Flores and couldn't/didn't want to wait for the van that had broke down to be fixed or another ride. We were fine with it but the guide kept asking us if we were sure. We finally convinced him that we felt ok with it. So bottom line, I think you'd be fine. They also had police or security all over the place when I was there last year.
