I'm not sure where else to ask this question so I thought I would go to the married life experts!
My parents will be celebrating their 40th anniversary this September. They were originally planning on a having an anniversary party but my grandma's 85th birthday is also in September and my parents are usually the ones to plan those types of gatherings.
They considered combining the two (my grandma only has a handful of friends still living and knows my other side of the family well) but thought it might be too much so now they will probably nix the anniversary party and just do a birthday party/family camp-out weekend at their house.
Is there any good way to combine these two events? I really don't want them to miss celebrating this milestone event since a lot can happen in 10 years before their 50th. I've considered a surprise anniversary party at their house or a local hall over the summer but that just makes 2 parties to plan for, buy food for, etc. (~200 guests) The size seems too large for an ordinary BBQ pitch-in. My only other ideas were doing an evening party (after 7pm) with just snacks and drinks and a live band starting around 8 during a cold weather time like Feb/March 2021.
Thoughts?
