What size Turkey Crown will i need?

[Deemented]

I know it's going to have to be a big one, but haven't got a clue what size i'll need.

With it, i need to feed

On Christmas Day
5 Adults, 3 children, as a main Christmas dinner

On Boxing day
3 Adults, 3 children, as in cold meat and chips

On the 27th
6 Adults, 3 children for a buffet type meal

I would also want enough to make sandwiches with too - there will also be cold ham available for all meals ect.

Any ideas?

Last year I had a 20lb turkey boned, rolled and stuffed by the butcher. It fed 8 adults and 2 children on Xmas day, enough leftovers for turkey curry (of course) cold meats and I left my MIL with some too. Plus with boned, rolled and stuffed you get the dark meat too...yum!
