What to include in invitations?!

If is an all in one venue then I think you have it all covered. You could put an order of the day insert to include ceremony time, drinks, meal etc. We are doing it all on our website through Hitched as is more sustainable than sending invites and is free so saves money. Our venue has several restrictions as it is a ruined Castle, so we have created a page on the website to put all that info on and links to our discount code for the hotel and taxi firms as well, I think having it all in one place on a website makes it easier for people these days as they can access it all easily and RSVP online as well and ask questions. It takes a bit of time to add your guests in but once they are there I have found it so easy to do my table plan and move people around when we have had people decline so mat be worth having a look at doing that?

We kept ours super simple (and didn't bother with a save the date). Date/time/location

I used Canva (it's free) and stuck a bar code on it with a link to a Wix website. (website also free). We then put all info on the website such as dress code/hotels/no kids etc etc. The website has a link on it so people can RSVP and put in any dietry needs etc. I don't know whether it would let you add menu options or anything like that. It's been so easy and I just get emails when someone RSVPS. Means people don't end up with loads of paper, don't need to post anything back and more importantly, I don't end up with loads of pieces of paper for RSVPS!

You'll need to include a menu and ask for food choices/allergens. Depending on location, you might also want to include information on parking and on accommodation in the area. We did a separate A4 sheet which included information on food, local parking, local accommodation etc, so the invite was just the date/time/venue.
