Which Game Pack Should I Get?

If you're more of a realism player, Parenthood is the way to go out of the four, though Outdoor Retreat would be a close second for those family vacations. Parenthood adds a lot more depth to playing families, plus I do like cheating some of the Parenthood traits onto the existing premades that I don't plan on actively playing. I also love the furniture style -- very homey and fun. I think it would go well with Seasons since so much of that pack revolves around home-based activities (holidays and events).
