We have many times travelled in an RV but this trip we're travelling light and will be tent camping and some hotel stays. We have a trip tick from AAA so our route is planned. We will be traveling for two weeks starting with Yosemite for a day. We're heading for Yellowstone, then Montana, Idaho and Washington. The question is, without knowing how long we will stay in each place, do we need to make reservations ahead for campsites, or hotels. Travel time is June 25th - July 10th. We kind of just want to play it by ear with our schedule but don't want to be turned away by camps or hotels that are booked. This is our first trip without an RV and a completely detailed plan.
