Trying to plan the last day of our trip to Tanzania. Considering getting an early (6am) start from Ngoro Sopa into the crater. Plan to spend 6 hours (could cut back to 5 hours if needed) in the crater so would therefore exit the crater at Noon (or could cut back to 11am if needed). If exiting the crater at Noon (or 11am) would this allow enough time to be back to JRO to catch the 8:40pm KLM flight? I want to allow enough time for unexpected events (e.g. flat tire). Does this seem doable or is it too risky? Would like to get multiple thoughts as to whether this is doable or recommended. Has anyone actually done this in the past? If so, how did it work out? Thanks.
