Is it easy to change a guest on the reservation?

When I originally booked my trip my husband was coming. Now my mom is coming in his place. Can I easily swap the names on the reservation online or do I need to call MS?

You can do it online by modifying. The only one you can't change is the lead guest.

I am listed first so I should be good then. Thanks
