I would always recommend a self-drive road trip if it was an option. Travelling by coach would mean that you would be a slave to someone else’s itinerary and unable to experience Route 66 on your own terms. Also, some group tours by coach aren’t particularly faithful to the old road and can take large liberties with their route. The charm of Route 66 is the freedom to explore at your leisure; being able to pull over whenever something catches your eye. You won’t get anywhere near this experience with a packaged trip.
However, that isn’t to say that a coach trip wouldn’t be enjoyable - far from it. If you really don’t think a self-drive road trip is for you then a coach trip is the next best option and will certainly give you a flavour of what the mother road has to offer.
