Owner Mark Goodson said he has sold five holiday homes and one holiday lodge, worth £330,000 in total since the Covid-19 lockdown restrictions were eased.
There are currently three caravan pitches left in the Old Park, while the Wayside Lakes Holiday Lodges development is well over half full, with only 13 lodges left to buy.
Wayside is located on a picturesque site at the village of Wrelton, between Kirkbymoorside and Pickering.
Mr Goodson said: “The demand for homes has been quite extraordinary.

“The interest in our park is a clear example that people don’t want to go abroad this year, and possibly not next year, because of fears about the coronavirus pandemic.
“The idea of a staycation in the UK is now incredibly attractive for many, which is tremendous news for our embattled tourism industry.
“Certainly the surge in sales at Wayside has taken me back to the time when we first opened 45 years ago.
“Once it was announced that we could open in early July, we were looking forward to an exciting and productive year following a record-breaking 2019, but we weren’t expecting anything like this.
“It’s been manic.
“To say I am thrilled is an understatement.
“Now, with the lockdown eased, our park is thriving.
“This is a very significant year for us with our 45th anniversary.
“My father founded the park in 1975, so it’s a time for celebration.”
