Russell Westbrook isn't letting the Lakers' early-season struggles put a damper on his spirit ... 'cause the SoCal native hit up the Happiest Place on Earth with his wife and kids.
The Lakers -- who last played Friday against the Clippers -- had the weekend off ... providing Russ the perfect opportunity to spend some quality time with the fam.
Westbrook and his wife, Nina, took their kids to Disneyland in Anaheim on Sunday ... where they enjoyed some rides at the famous theme park. And yes, they had delicious Churros too.
