There is charges on the bus but only for phones or ipods or camera battries.
Usually drive day would be split up by breaks every 2-3 hours so the days go pretty quick.
I wasn’t a sleeper on the bus so when everyone else slept after a big night (ie. every nite) i would annoy them by taking pictures of them drooling in there sleep or just relax and listen to Music.
We would also have story time each morning which would consist of everyone putting in there favourite funny stories from the city we had just left and then we would vote on the best story and there was some really funny moments.
Then some times we would play games ie. name the song and artist, name the tv show for the theme song, battle of the sexes but us guys always lost. Impromptu Karrioke usually when we were excited about entering a new city we would all just start busting out some tunes, people driving past probably thought we were a “special” bus with 40 odd people singing and dancing in there seats and up the isle. Also had games when people had to do push ups for saying certain words which always keep your mind active.
I highly recommend moving around the bus and chatting to as many people as possible especially all in the trip to get to know people. But chatting was the most common thing to do as there was always stories that needed to be told from the night befores party.
