Sundown Adventureland is a firm favourite with Nottinghamshire families with children under 10.
But while those under 90cm get into the fun filled attraction for free, adults and children over 90cm pay between £15.00 and £21.00 depending upon age and the time of the year.
However, the park has just announced that there will be a weekend of discounts to celebrate Mother's Day this year.
Mums and mother figures heading for the theme park near Retford will be offered half-price tickets on the weekend of Saturday, March 26 and Sunday, March 27.
Mums will only have to pay £10 for a standard adult ticket usually priced at £22.50.
Park director Debora Griffin said the weekend held significance and reflected on her late grandmother, Audrey Rhodes, who founded the park out of her bungalow back in 1968, reported Lincolnshire Live.
She said: "Sundown Adventureland is a family-owned park, opened by my beloved late grandmother, Audrey, who was always so passionate about giving something to the local community and providing a special place where families could be together.
"We know how important it is to celebrate and treasure special memories and have fun together and we hope families will come together this Mother's Day."
The park will be open over the weekend from 10am until 5pm.
Mrs Rhodes died at 92 in March last year.
The theme park reopened for the public in mid-February, and will now remain until Christmas Day - except for a two week period in November.
Overnight accommodation is expected to open later this year.
