The500man,
Personally I look forward to the day I can get in my single-pilot spaceship and go for a bimble round the solar system!
Funny, that's always been a little daydream of mine as well! Keep it in the shed, pull it out when required, get strapped in, and by this time it will be so user friendly and regulations will be so harmonised that you can just fly it off to space like a light aircraft! If you think about it, if you plan on travelling in straight lines (or, to be more accurate, working out your 'voyage' so you require no vector changes enroute), you won't actually need much fuel once in space, only that to speed you up to cruise, and to slow you down again at the end!
It's just the 'getting it up' that's gonna be the problem!
Ah yes, I can dream...
