Breakfast of champions!
Despite their amazing day hanging with dolphins, Chelsea's dad, Randy Houska, showed fans that there was a bump in the road trip.
Their flight was cancelled! Chelsea tweeted, "Nothing like hauling 1838 suitcases, 7 year old & a baby to the airport just to find out our flight is cancelled & we can't leave till [tomorrow]." Yikes!
But they still had a great time and even found Nemo.
The whole crew! Looks like MTV fans will get a glimpse into their first vacation as a family of four.
