If you are spending Hyatt points, you can book a Guest of Honor and guarantee breakfast and other benefits for your parents' room.
Otherwise you need to do a bit of research to find the stingy hotels, but you could probably manage to get BF for both rooms when both are in your name. Marriott as well FWIW. None of the chains guarantee benefits beyond the member and one guest.
With both Hilton and Hyatt you can earn all of the points from two paid rooms in your name.
