Garner stayed with their three children in a resort while Affleck crashed at a house nearby.
Affleck is currently training for a new movie, Triple Frontier, in Hawaii and Garner reportedly decided to take the children to their father for the religious holiday. The family visited Sea Life Park where the kids were able to interact with dolphins and sea lions.
"They spent several hours at the park and looked like they had the best time. The kids were all very interested in learning about the animals. They all seem like huge dolphin fans," a source close to the family stated.
The Alias star reportedly brought a female pal with her while her ex-husband spent time with their children.

Will Ben and Jen Reunite?
Garner and Affleck had an 11-year relationship, from 2004 to 2015. The couple married in 2005 in a private ceremony that was officiated by Garner's Alias co-star, Victor Garber. Their three children, Viotet, Seraphina, and Samuel, were born in 2005, 2009, and 2012 respectively.
In June 2015, the couple announced their separation and intentions to divorce. It was later reported that Affleck cheated on Garner with the children's nanny. The former pair has been focused on raising their children and still remain amicable towards each other.
"The kids love when they all spend time together. As long as Ben keeps working on himself, Jen is happy. She will continue to support him because it benefits the kids," another source told People.
However, fans shouldn't hold their breaths about Garner and Affleck reuniting as Affleck is apparently "committed" to his current girlfriend, director Lindsay Shookus, whom Affleck has been in a relationship with since 2017.
While there haven't been reports about Affleck and Shookus walking down the aisle, the two reportedly are "enjoying each other's company."
