So our intent was to have one party but now it looks like we will have two parties. At the moment, they will be a week apart! Whoah!

Each side of the family has their reasons for wanting a particular date so we are having two.
It's going to be hosted by family on each side.

Anyone do this? Twins will be 2.

Not sure if we will do printed invites. Trying to keep this low key for both hosts and us.

For inviting friends, do I just tell them we are having both parties and they can attend whichever one works for them?

ETA: I know this can be a common issue with some having a kids party and a separate party for relatives/family.

Any tips?

Both parties will be in PA where almost all of our friends and family are.
