We have gone once before but stayed in a hotel and it was just 2 nights. We did the some easy hikes accessible from the tram but it was winter so we just stayed around the main area and then did the Valley Floor bus tour. We are going in the summer for 4 nights at Housekeeping Camp this time. Any thoughts on must see places outside of the main area? Any items you wish you brought and didn't or things you brought but didn't need? We are recreational hikers and novice with the great outdoors in general.
