Is there a Disneyland park ticket discount available for only 1 day / 1 park?

Hi

I am looking to purchase two tickets for family members who are only joining us for 1 day at Disneyland. They would apply for the special $99/2 day 1 park special but wont be coming back within the year. Are there any discounts out there for single park admission?

Thanks so much!
