Changing the "Reservation Contact"

[evlaina]

We are booked 9/29-10/4 at Beach Club. Decided to come in a day early (9/28) and stay at Pop Century. My in-laws decided to join the trip and are staying straight 9/28-10/4 at Pop Century. Therefore, my in-laws can make ADRs 1 day before us for the whole trip because they don't have a split stay.

I am handling 100% of their planning and we are linked on MDE. Can I log in as my mother in law, change the reservation contact to myself, and book all of the ADRs 180 days from 9/28?
