"Trip Advisor has been amazing for us. We haven't got a day spare until March 29."
Mrs Keay said they put in extra effort so people would enjoy their stay.
"I think being friendly, accommodating and giving people what they want most, and being right on the water, that's what makes it I think."
Mr and Mrs Keay were planning to sell the house and the business to be able to be closer to their grandchildren.
"We have made a big decision with regret and excitement.
"It is a great business and a real credit to Rotorua is how people enjoy it so much here," Mr Keay said.
Arista of Rotorua took out the number one spot in the Top 25 Hotels for Families in New Zealand, as well as placing 10th in the Top 25 Hotels for Families in the South Pacific, and 24th in the Top 25 Hotels for Service in New Zealand.
Arista of Rotorua owner Mike Gallagher was chuffed with the placings.
"Rotorua, as a whole, has done extremely well on the awards this year and we think this is fantastic. We see Rotorua doing really well in the coming two years so its about local accommodation providers trying to work out how to capitalise on those two years."
"I think it's awesome for Rotorua. Overall Rotorua has done really well because what it shows is that we all work bloody hard to give a good service and to give a good tourism spiel because so often we get tourists come here first, and then when they leave they say we in Rotorua were the friendliest people in New Zealand."
