When I was 9 I was so busy. How about day camps? Went to loads of those - for dance, crafts, music lessons, etc. Lessons - lots of those, too. Art, swimming and the like.
We also learned early on how to entertain ourselves, and it's a skill I'm very grateful to have been taught, for it's served me well in adulthood. Put the older one in a few art lessons. Then get her a paint set or pencils and tell her to go amuse herself. 9 is old enough to not need constant attention from Mom.
Our 2-year-old daughter is out at least three days a week and sometimes - playgroups, TumbleTots, swimming. I check and find out whenever any of the museums, libraries or tourist attractions have something going - most of the time it's free and gets them out for at least a few hours.
How about joining a gym? Many of them have a creche for kids for a small fee.
My mom's secret (she was a SAHM) to having time to herself was to carve it out for herself by keeping the kids involved in activities.
As for the getting up, there're several ways to deal w/that. Revoking privileges for getting up too many times is one way to do it. My folks didn't care if we didn't go to sleep after lights out, so long as we didn't bother them. When we were younger and complained about being 'bored' or 'not tired', my dad would then come in w/the Rosary. B/c if you weren't tired, then you had time to pray. And once he got started, we had to stay up thru the entire prayer. We learned quickly to occupy ourselves in bed.
