We are staying 5 nights at the Mauna Lana mid November. Would like to see vnp. Traveling with 81 yr young mom so no long hikes but would like to see the volcano and other stops. Saw a post that we should plan 5 hours at vnp? Is that accurate considering we will not be hiking? Understand driving back at night is not advised. Leaving very late on 6th day. Whats the best plan?
