Around here there are pumpkin patches - hay rides, corn mazes, farmers markets.

I forgot - you have 9yr old, 13 yr old and 15 yr old that are your fiances kids.
The teens aren't going to want to do much except hang out with their friends.
The 9 yr old might like some of the stuff mentioned above.
If their dad will be away all week - isn't that a good time for them to be spending with their mom?
Perhaps you could enjoy a kid free week and get together with some of your friends.
It could be an 'everybody take a break from blended family' week.

This is a public forum and you asked a question.
You don't get to specify how people respond.
Take what you find that helps you and ignore the rest.
You have an awfully interesting life for a 21 yr old.
It's a bit too interesting and I'm starting to think that you are a troll making things up.
The whole 'I never got a chance to be a mother because I chose to serve my country' thing is just really strange - you've got roughly 30 years till menopause.
And now you're a student.
"I've received my bachelors in public safety and emergency management and I’m going to school to be an esthetician"
- that's quite an accelerated program for a 4 year BS degree by 21 - did you start college at 17? -
and now also a part time model for Harley-Davidson besides being a live in nanny who's sleeping with her boss and calls it an engagement.
And in spite of being only 6 years older than the oldest child you are looking after you can't figure out how to entertain the kids while their dad is gone for a week.
Your fiances step sons mother passed away but the biological mother of the other 2 doesn't like you and it doesn't sound like the kids like you either.
Where are your parents in all this?
Apparently they don't care enough to supervise your computer use adequately.
Just put the computer down and go read a book.
You sound a lot like a 'grad' student who trolls here sometimes making up impossible situations for people to respond to.
It's doubtful any tale you spin has any basis in reality.
I delete hate mail so don't bother.
