Invite wording

I agree with saying Cocktail reception and we are kind of doing something along the same lines. We are having guests RSVP through this site and since there is no meal choices I created a FAQ section and wrote this:

1. I don't see an option for what I want to eat, are you going to feed me?

Yes, don't worry - you won't go hungry! We are doing things a little differently by not having a formal sit down dinner. You all know us and should recognize we'd rather have a fun, mingle type setting. We will be starting off with lots of Hors D'Oeuvres and then moving to a couple chef manned action stations with super-delicious dinner choices. There will be a mix of traditional tables for sitting and cocktail tables to stand at when you just feel like a snack. There will also be dessert service with a few yummy selections. Please do let us know however if you have any dietary needs.

If you say "Cocktail Reception to Follow", people should know that means the less formal, appies/drinks option. Not really seated tables, but more of a party atmosphere. If you are utilizing the Wedding Wire wedding website builder, you can add on your wedding details page that there will not be a seated dinner, but passed hor d'oeuvres and drinks. (easier to be wordy on the website, than on your invitations).

Our invitations have the start time to the ceremony then say "cocktails, canapes and luncheon to follow". I'd just put "cocktails and canapes to follow" (or hor d'oeuvres or tapas)

Stephanie's phrasing is great, or even "Ceremony at this time followed by cocktails and light refreshment" or "followed by a cocktail reception to follow"

I would say "Ceremony at this time followed by an hors d'oeuvres reception at this time"
