I must commend your resolve, landing safely on Mun without having the quicksave feature isn't something I even dared to try when I played the demo.
Now get them home safely to Kerbin.
By the way, if you're planning on getting the full game, it's better to get it sooner than later. They increase the price with every major update, and it went up by $5 the other day because they released version 0.18. It's worth it though, the latest release is amazing and finally allows you to dock ships to one another, and it allows you to build unmanned spacecraft. It completely redefines how I play the game.
This is a space station I started work on. I used an unmanned tug to bring it into a 200km 45° orbit, then the tug undocked and crashed back into the ocean.
Next up, I added the first solar array to power the station.
The latest addition is a crew module.
My rough plan for the station involves eight more trips to complete construction, and two additional trips to add crew.
