You have some good advice from Kristina, Tim.
This is a hot button issue here, as you will discover if you read a few of the discussions. I added my family manually and I think the advantage is that you can make sure the information and formatting is correct. And you will learn things along the way, too!
The gedcom process is involved and requires work to cleanup the profiles afterwards.
So, definitely give this some thought and try making a few by hand first. Then try a very small gedcom, if you decide to try that option.
It's your choice, in the end.
