It might be better to surprise him later, to let him know that, without realizing it … they were already on their honeymoon.
"Since it'll take us several days to travel to Moonshadow and come back," Primrose began, "We'll probably need to finish all our work before we leave."

Edmund stared at her blankly, but inside his mind, everything was in chaos. [WHAT?! NO! I want to see my wife every single day!]
[But … she's right. I do have too much work, which means I'll probably be stuck in my room most of the time.]
[Wait—what if I ask her to work in my room too? Then we can still be together!]
Actually … that didn't sound like a bad idea.
