In what was a rollercoaster of a year for the Sim family, a house on the shores of Lake Rotorua offered a place to get away, even if it was only for a week.
Throughout 2017 Carter Sim battled Alagille syndrome, a rare condition affecting his heart, liver, lungs and kidneys.
After liver failure and a transplant the year before, a tumour was found in Carter's kidney in April 2017.
Now 4, the little boy went through months of chemotherapy and radiation. He was in hospital just before Christmas and only released three days before.
That's why the week the Napier-based family spent at Ronald McDonald House Charites' only retreat was such a blessing.
