“Save the Evening” cards

We only did save the dates for our guests attending the whole thing. I would be cautious for evening ones as if you send and then you then wanted to bump them up to a full day guest if you have drop outs as it can make people feel a bit like they were an afterthought and weren't good enough to make the cut initially. I honestly have never heard of it so I don't think is necessary.

we had a list of evening guests but asked our day guests when we sent the save the dates to let us know ASAP if they knew now they could not come. we got 6 back straight away declining which meant we could bump evening guests up and sent them save the dates for the whole thing a year before, which allowed us to have our lists locked down fairly early on. We then sent messages and an email to the evening guests 8 months before to let them know, which I think was more than enough time and then official invites went our 4 months before to all guests
