I organized my family’s short trip, which was my older sister used to do, but she is busy working every day, so I ended up taking charge of planning this trip. I wanted to do something active, so I added some attractions to my plan. One of them was a paragliding. My family had never done it before except for my dad. (He did it in the army when he was in his 20’s.){There's no need to put in the brackets.}
I can’t wait, and it will be a thrilling trip! There is no exception. Everyone should follow my plan.        

Note: Your last 2 sentences sounds rather "hard & strict". You can actually say" I've encouraged everyone to follow my plan."

Good try!
