As others have said, it's doable to attend the ceremony, sightsee during the day, and then you and DH go to the reception. But if there's no one to watch your kids that evening, then it's impossible for you to go.
This is really it. Although I think the schedule is strange and irritating. Even if I was single, I'd rather have the whole day to do whatever, and the wedding and the reception together in the evening. Sure, you can sightsee or something, but you either have to go back to your hotel and change and then go back to change again in the evening, or walk around all day in your dressy clothes. Sounds like a pain.
Unless you're really close to your niece, I'd just decline and send a nice gift.
