It is about control.

Kids are just too many cells for them to keep track.

One nice thing about "Going to Disneyland" is that it's a perfect excuse for a person to spend a long weekend in California and come back tired. It's open all year long, and is so crowded it wouldn't be odd if another person was there at the same time and never saw you. It's easy to know what kinds of rides, food, and experiences one might have enjoyed, and appropriate souvenirs are available at LAX, you can stock up before you even leave the terminal. Whether you actually spend your time visiting Planned Parenthood and recuperating in your hotel room (or an Auntie's spare room) is entirely your business. Although spending some time in the noonday sunshine acquiring a toasted nose will add verisimilitude.

Editing to add: You could even get mifeprestone and souvenirs (for nosy coworkers) all delivered to your home in plain brown boxes and "Go to Disneyland" in the comfort and privacy of your own bedroom, if you're little enough along.
