My mother and I took a bus 'tour' of the Pacific Northwest about 10 years ago, so I don't know how relevant our experience was. It was really nice to have someone else do the driving, make reservations, tote the luggage, provide a narration of what we were seeing. However, it was not so nice when a few members of our group insisted on dawdling at each stop and making the rest of us wait on them.
It depends on what is included in the price - if they make all the arrangements, I would definitely say yes, especially if it involves show tickets. If not, are you good at finding and making reservations online? I think based on your location and the destination, I'd definitely look into it, but ask questions of the tour company. You don't want to be stuck on a bus full of teenagers, for example (well that depends on you of course
)
