The Lacheys sure do know how to have a good time!

On Wednesday, Nick and Vanessa Lachey took son Camden John, 4, and daughter Brooklyn Elisabeth, 21 months, to Disneyland for a day of fun — and thrill rides!

“I’ve been waiting for years to ride a rollercoaster with my son!” the proud dad, 42, captioned a snap of the soon-to-be family of five posing in front of Sleeping Beauty castle.

“Thank You @disneyland for making this happen! #ThunderMountain #Matterhorn #SpaceMountain,” he added.

“Thank You @Disneyland for a magical day!!!” Vanessa wrote on Instagram next to the same group shot showing her and Brooklyn sporting matching Minnie ears — the latter also rocking Minnie-inspired kicks. “The ‘5’ of us had a blast! Can’t wait to take littlest Lachey next time!”

“We talked about three,” Vanessa said in 2013, adding jokingly, “I’ve always loved having a big family and truth be told, when I’m old and gray I’ll need a couple of them to take care of me!”

Luckily, her singer husband is on the same page as far as the ideal size of their brood — and enjoys his role as a family man more than anything in the world.

“I’m very excited to be a dad again,” he told PEOPLE in 2014 before Brooklyn was born. “My dream in life has always been to have a family. It’s surreal when it starts to happen before your eyes.”
