help me to help my parents renew their vows

My mum & stepdad have now been married for 10 years :clap: A lot has happened in that 10 years, and i'd really like to help them renew their vows. They have always wanted to rewnew their vows on their 10th anniversary with their kids there, but unfortunately my dad is no longer in contact with his kids.
They were married in Darwin with no family around, just their closest friends as they were doing a Qld/NT trip at the time.
I live in Cairns (as do my parents), my sister is on the Sunshine Coast, and my brother is in Perth. So I'm not really sure how this is going to work.
I just want to organise something little for them, but something special as well. Their anniversary is also the same day my stepdad's father passed away a couple years ago, so they haven't really celebrated their anniversary since his death. I have spoken with my stepdad about this recently, and told him that maybe it's time that he started celebrating his fathers life, rather than mourning his death. And he agreed that it's time to do that, and also time to start celebrating their anniversary again.

So what sort of thing can I organise? Where should I organise it? I would love for them to go back to Darwin with at me & my siblings.
Can anyone help?

maybe speak to your siblings and try and get in contact with your dads kids and organise for you all to put in and meet in darwin for their anni also try and get the same celebrant/preist who married them the 1st time!

My friend couldn't afford to renew her marriage vows on their 10th Wedding Anniversary so they DID it on their 15th instead ... It was so lovely under a beautiful old rotunda at 11.30 am on a sunny Sunday morning ... They walked together as a Family (all 4 of them) down the path leading to the rotunda ... They had a female celebrant who spoke about them & in turn the couple each gave a beautiful speech to each other ... we then had a lovely lunch at a fancy cafe on the park grounds in which they booked the table.

They had her parents (his have since passed away) ... and their two daughters (6 & 10) ... and a best friend each there with their partner & child/children.

I felt quite honoured to be there with my DP & my daughter who was only 4mths old at the time :D
