Hardest part will be just starting and putting it back into first in a timley manner. Hills are very scary at first. It helps a lot to start using the handbrake. Handbrake so that you dont roll back and rev the engine - from there it's like regular shifting into first. You will still roll back, but not as much.
It's all about patience. After you get the hang of it (which you will even if you think you won't) it becomes second nature. Not more work at all.
