But we need your help! We know many of you love an excuse to dress up and enjoy a theme to inspire your outfits.
We’ve been loving look back at the pictures of ‘When I grow up’ in 2016 and ‘Safari’ last years – what shall we have this year?
Share your theme suggestions on our facebook post, the only criteria is that it is suitable for all the family.
Inevitably the best suggestions will come from our younger party goers so please ask them for their suggestions. We'll put them to the vote and the winning theme will get an age appropriate prize.
See all the photos and videos from the last two years here.
