Contiki Tour Bus

Hello all,

Just got a question about the Contiki bus. Is it comfortable? The trip I'm doing (European Explorer) means that the majority of our bus trips will be 5+ hours. Also, I have seen a few videos where it seems like the bus is a year 10 high school party bus where people are jumping up and down, screaming, singing and all the rest of it. I mean once every so often doesn't bother me but will this be happening constantly?

Also, is there a powerpoint for every seat or just one in the whole bus?

Thanks in advance
