18 passenger tourist spacebus (for kerbin orbit)

[not enough fuel]

in the early game for the ferrying tourist contracts i kept adding mk1 crew cabins and ended up with my max feasible to be 9 for 18 people to get into orbit.  i made a lot of money from it early game and upgraded a lot of facilities.  but now that i've been to the mun and minmus they want to go there so i stopped taking requests >:(  don't think i could make a ship that could go to the moon and back with that many people and be economical.  now i have to make money the old fashioned way. but i'm a bus driver at heart. i'll work on satellites instead.

but i tweaked it until it was successful and this is what i ended up with
