I just remembered one of my girls ultra-favorite ever gifts: Private driving lessons.
Okay, not something you'd get for your niece, but my daughters were thrilled. In our area public school driver's ed is "backed up" so students can't get a seat until they're almost 16, so they're delayed getting their permit, and then they're delayed getting their license. It's also something like an hour 3 afternoons a week Xs 6 weeks for book work, then wait again for your turn behind the wheel.
On the other hand, private lessons were 3 all-day Saturdays. Total.
It cost about $300 -- this was almost a decade ago. When my oldest opened her homemade gift certificate, she started screaming, "This is a choice? For real? This is a thing? And I'm already signed up?" It was less of a surprise for the youngest, of course, but I'd go this route in a heartbeat if I had it to do again.
