My parents are coming to visit next month and we want to do the Railway out of williams to see the grand canyon as my parents are a bit older and can't exactly hike. Are the higher classes or the 1.5 hour bus trip around worth it? We are not very picky to see everything but would like to get around a bit. Also if we do not opt into the higher class that includes lunch, is it best that we bring our own or will there be a stop in town at some point where we can eat? Thank you in advance
