My fiance and I have a large network of acquaintances, mostly because of our work. It has become very clear since we got engaged that they are expecting to be invited to our wedding. We have both worked in the same industry and city for about 8 years, so we have known a lot of these people for a pretty long time but we wouldn't consider them our close friends.
We are paying for the wedding by ourselves and realistically can't afford to have more than about 100 people. We have done a good job cutting our guest list to about 80 people, leaving us a little wiggle room. If we included these work friends the list would probably be around 250+ or so.
I would like to find a way to include these people somehow in our wedding without tripling our guest list. A co-worker in the same predicament did a pre-wedding party (not exactly an engagement party though) and it was basically an open invite to an upscale bar. I don't think they paid for any of the drinks, but maybe had some passed hor d'oeuvres and a few bottles of champagne. I thought it was a nice idea, but know that I am considering planning something like this for my fiance and I, I am feeling really unclear about how to do this and not be totally tacky about it. (Come to our engagement party! But you're not invited to the wedding!)
I know the simple answer is to just say we are having a small wedding with family only and then not worry about it from there, but if there was some way to include all these people with out breaking the budget I would love to hear it!
