Marcia Cross Santa Monica Pier park rides carousel sunglasses jeans scarf twin babies kids

Marcia Cross is so in love with her 4-year-old twin daughters, Eden and Savannah ... and it shows!

The Desperate Housewives actress took the little girls to the Santa Monica Pier for an afternoon playdate.

Marcia's husband Tom Mahoney is nowhere in sight, but since he's a stock broker, we have a feeling he's busy working those non-stop deals. Good thing mommy has time for the girls now that her hit ABC show has wrapped for the season.

See one of Marcia's twins having fun in a helicopter ... after the jump.
