Get together is definitely not just a party pack. I use it a lot because I am an ambitious player. I create a specific club for maxing out a skill faster. When I look for a spouse for my sim a create a dating club. Sometimes if I want my sims to avoid their duties and do something fun instead, I create a club where members clean and tend the garden,... instead of my sim >:) Also, one simmer here on the forums creates family reunion clubs. For example. The mom is in a club where the members are her branch of family, the dad creates a club with his family members, etc. The club activites would be be friendly, hug, eat. You can have up to 3 club gathering on a lot at the same time. It is really awesome if you play families :)
