We were able to get reservations to see the sunrise on Friday morning. We haven’t done this before - any advice? We are staying at the Marriott Courtyard Kahului on Thursday night. Any idea how long it will take to get to the summit? Normally it would be a little over an hour but the website said to plan two and a half because of traffic. Is it really that crowded heading up? Will restrooms be open somewhere up there that early or should we skip our morning coffee??? Any other advice?
