I just found out about this interesting haggadah: Human Rights Haggadah The above link has some actual pages from the haggadah so you can get a pretty good idea of what it is like.
This year for Pesach we are hosting a second night seder at our house. The four "kids" in attendance range from age from 17-25, so I'm thinking that rather than have the youngest one be saddled with asking the Four Questions, I may suggest that "all attendees under age 30" can jointly sing the questions (the other attendees are all over age 50). Furthermore, I expect my kids will happily enjoy collaborating with the other kids to snag and hide the Afikomen, so I think I'm going to buy two copies of the Human Rights Haggadah, one for each of the two families, to use as Afikomen "ransom" gifts. All of the kids have an interest in human rights so I think they will like it. I was thinking before of using the graphic novel haggadah as Afikomen gifts, but I don't know if the kids of the other family like graphic novels and if they might feel that it seems more appropriate for younger kids (although there is more respect for graphic novels as a serious art form these days).
We are going to the synagogue first night seder. I'm not sure if we'll do a second night seder - there will be only us and one daughter visiting. Maybe I might invite another couple? I don't know very many, and the ones I know don't have children at home.
When it is just us, or just the family (us and the girls) we usually use that 30 Minute Haggadah, which covers the bases!
