Recently Engaged, party ideas?

Hi!

My partner and I got engaged recently and have just booked our local rugby club for our engagement party at the end of next month!

I was hoping you ladies/gents could share some ideas or tips for our engagement party? We've got the venue and entertainment but I can't think what else I need to arrange! This is our venue set up for another function

My lovely fiance designed my engagement ring and had it made for me with our birth stones in a yin and yang, so thought I'd share a picture!
