That's not a problem, Doug. By the time you've planned to have it ready, no-one has any appetite left anyway, what with filling up with the crispy bacon, a quarter of sugared almonds and those nice long chewy ones out of the Quality Street tin. Besides, the house will be hot and clammy with steam and cooking smells and you won't be able to sit where you always sit, none of it conducive to wanting a plateful of food which includes overcooked sprouts, bread sauce that would be better referred to as wallpaper paste and that nasty sweet-sour red stuff that ruins the taste of everything else on the plate. Just give everybody a few more slugs of Prosecco and a couple more hours...
