It was a pretty short ride once the bus came, so I would allow at least 30 minutes--20 minutes for a bus to come to the stop and a 10 minute ride. DHS seemed like the shortest bus ride we had from CBR.
One bus driver told the bus riders to allow 1 hour to get from a resort to a location in a park--20 minutes for the bus to come, 20 minute ride and 20 minutes to walk to where ever you are going in the park (like a restaurant).
We had fairly good luck with the busses at our recent stay at CBR--sometimes it felt as if every other bus came except the one we were waiting for but that was probably because we ere so anxious to get going!
