Save the date wording

Hi all! We’ve just ordered our save the dates and I now need to send over the wording we want on them. I don’t want to over do it or under do it. Can anyone give me advice of what should actually be on the save the dates? My current plan is


Save the date You are invited to the wedding of blah and blahLocation - but just the area not the venue? Formal invitation to follow
Is there anything else that would be needed??
Thanks all
