Help! Need a quick answer. After us having the most awful year for my poor DH's health we have decided (madly) to have all of the family over to us, possibly 10 adults and 3 kids. So, i was a bit late sorting this all out and cant get a waitrose delivery to home but can get a collection from te shop right up until xmas eve morning for the turkey etc. Has anyone done this before? Will it be a nightmare? will they have run out of food? Will it be elbows at dawn? Thanks to anyone with an ounce more experience of this stuff that me.
