It is where you spend about 1/4 of your summer in (sometimes longer), so the need to be comfy in the bus is very important.
And yes, the need for "bus boxes" are very important. They contain all of your bus snacks (which are life savers for all-night bus rides), any small souvies you buy on tour (patches, programs, etc.), and anything else you want on the bus (books, music, movies). Other than that, you can have little white boards to hang on the windows, or anything else to entertain you and your seat partner.
