How long do you expect people to stay up there. At the cost of training and sending them up I would expect at least a three month tour of duty, more likely six months. Now for the off the cuff calculation. 3 Days transit time * 2 people * 26 times per year = 156 man days wasted In sending people back, not to mention all the payload lost due to having to carry the people, fuel and oxygen. Better to send plants and nitrate to make oxygen on the moon. The faster a moon colony is self sufficient the better chance of it surviving.
