I haven't tried to do that, but I do know that it doesn't work the other way around. Repeated requests from different posters to order the lunch burger at dinner have been denied. So it might depend on what your DH wants to order.
I wouldn't assume that the menu you're seeing now will be the menu by the time the Halloween parties start. But if you still prefer the other menu, why not just take the first dinner seating or go on a different day?
How do you know when the Halloween parties are on yet?
