The condition of me forking out a small fortune for our three tickets when they first went on sale months ago, was that the girls agreed that would be their Christmas present.
I now wish I had videoed them screaming, "Yes! Yes! Of course just please get the tickets, Mum."
I know that come Christmas morning they will still be expecting something under the tree, which is still in the forest at the moment.
This is my most disorganised Christmas ever. But I have to admit I have actually enjoyed doing nothing Christmassy yet.
There is so much focus on present buying at Christmas but if I think of my own Christmases past, I cannot remember any one gift that stands out.
What I do remember is laughing around the table, the silly jokes in crackers, lighting up the Christmas pudding, making snowmen during a memorable white Christmas.
Creating memories with gifts is becoming popular, writes Dawn Picken today on page A14.
I loved reading about Tauranga's Paul Bloxham who was surprised by his partner one Christmas with a shark dive and he laughed saying he wondered if she was trying to kill him. But then seriously he said how special that gift was, as he had a lifelong fascination with sharks. Mr Bloxham sums up exactly the idea of "experience giving".
"She looks for ideas rather than buying a phone or tablet or pair of shoes. I guess she buys memories rather than commodities. If you buy a cellphone, in two years' time you chuck it away. You never forget time diving with a shark."
Another non-material gift to give at Christmas that will make memories is a good deed. This week a story from Britain went viral about a man, Luke Cameron, who had been doing a good deed every day for the past year, and blogging about it on his "Good Deed Blog".
He writes on his blog that he had been inspired to do that after the death of a family friend from cancer last year. His good deeds ranged from simple things - like sending his colleagues morale-boosting handwritten notes, to paying for people in the queue behind him at Maccas, baking cakes for friends or simply remembering to phone his grandmother to tell her how much he loved her.
Even just one good deed can make someone's Christmas.
Each year reporter Amy Wiggins co-ordinates the Bay of Plenty Times Christmas Appeal for the Tauranga Community Foodbank. She remarked this week how people had been so generous throughout the appeal telling me how each year she is blown away by the stacks of food that pile up in our reception, and how giving people had been in the door-to-door collections.
"When we were collecting door to door I was humbled by the number of people who came out with armfuls of food and then went back for more. So often it was those who appeared to have the least that gladly gave the most."
Good deeds don't have to take the form of big appeals. This week during a frantic visit downtown I was about to pay for my parking ticket when a lady tapped me on the shoulder and said, "Here you are - take mine as it's got plenty on it." She didn't look like she had much and was driving a clapped out car. I offered to give her the money but she said, "Don't be silly, Love, if you can't do good deeds at Christmas, when can you?"
The specialness of that moment far exceeded the few dollars of the parking ticket.
So I don't feel bad about not spending a fortune on presents this year. As well as Perry, we will be doing the Bay of Plenty Times Christmas Light Trail, which creates such wonderful memories and doesn't cost a dollar.
This Christmas experiences and memories offer so much more than shop-bought gifts.
Selling that concept to the kids is proving a memorable experience all of its own.
