Christmas Eve is Saturday! Looking for something fun and festive to do before the evening activities commence? The Sacramento Zoo is hosting a Christmas Eve pajama party. Pick out your favorite holiday PJs—I found some adorable reindeer PJs at Target—and head to the zoo. Admission is free, but the zoo is open limited hours: 10 a.m. to 1:30 p.m. Stop by, and wish the animals Merry Christmas.
