Every single time I have dropped people from
my reservations it will give you the original time back as an option. I make dining reservations all the time and quite often end up modifying the party size. If you are truly clicking “modify” on a current reservation and all you change is the party size it will always give you your original time. At least on the computer version of
MDE. I can’t say I’ve used the app to do this. New reservations and/or trying to change times or restaurants is different. If you are only trying to change the party size this has always worked for me!
