Dear [Title] LAST,
Thank you very much for inviting [me / us] to [lunch / dinner / event] on [date].
We would have loved to come but unfortunately we [will be out of town / had to visit a friend who is seriously ill / had a prior engagement that we cannot cancel] so we will not be able to attend.
[We wish every success to your [event].] [We hope that you will have a great [dinner / party].] Let’s catch up again soon.
