We love national parks and hiking. Gros Morne looks lovely. We would have to fly into St. John's. We are looking at a 5-7 day trip. Does it make sense to drive up to Gros Morne and would you then suggest any days in St. John's, as well? Or in that amount of time, do we really need to concentrate more on staying in the St. John's/ Trinity area. Can you tell us about travel times? Also, are we going to have a hard time booking accommodations so late in the game? Thank you!
