I am getting close to being tired of yet another holiday (next one coming up in two days), so I feel you. I usually invite the entire extended family over for more fun. I want to spend the holidays (harvestfest or winterfest) on vacation in Granite Falls in a nice big cozy lodge with the entire extended family with several toddlers, children, adults and pets. So people can bond, do activities together like hiking or fishing and whatever else you will provide them with in their lodge like a sauna etc. I regularly do big family vacations (14 people plus pets) in Granite Falls or Sulani so should be nice to spend the holidays there. This will also get repetitive but at least the younger sims in the family will have different ages year after year, giving you different interactions and activities.
