I have secured tickets for MP and HP in the same day. I will be spending the night in AC the night before our big day in MP. I am planning to catch the sunrise at MP and then leave for our HP hike at 10AM. I'm hoping to make it back to MP by the time most tourists leave and then take a train back home that night. Does this sound reasonable? How long does the HP hike take? We are a couple of relative fit people. I just want to make sure I'm budgeting enough time for everything. TIA!
