Helping my niece plan her portion of the trip from CA to YNP. She is looking at seeing Twin Falls, then on to Idaho Falls for the night (July 29) before meeting us in the park the next day. It will be too late to go on in to the park. So, anything she needs to see in Idaho on the way to Idaho Falls? And any recommendations on lodging once there? Was considering camping, but looks like that is out. Doesn't need frills, just clean and affordable- mom & pop or cabin places are fine. Also, may need a recommendation for dinner, depending on arrival time.
