We are not inviting coworkers to the wedding because my parents are paying, and they had so many people for the guestlist that we don't have room at our venue to add on to the guestlist. It's also kind of a weird situation because my job is a year position (August to August), and I work closely with people, but I am not sure how much we'll be in contact when I leave in August. I don't know what their expectations are, but I kind of guess they aren't expecting to be invited.
Anyway, one woman from my office offered to organize a dinner at a restaurant near my house to celebrate the engagement where everyone from the office that wanted to would take my FI and I out to dinner. Do you think I should graciously decline, or is it ok to accept? I know it's not polite to tell people they aren't invited, but do you think if I accept, I should mention something like "we're glad we'll be able to celebrate with you, since our guestlist was restricted for the wedding" or is that unnecessary?
