Some of these costs are bonkers in both directions!
I think we'll spend in the region of 250/300ish for 5 people from 24 - 27th December, including wine etc. Only 3 drinkers and one is very moderate.
I will do most of the shopping in Aldi as we prefer it to M&S having taste tested over the years.
We eat lunch out on Christmas Eve, cook the ham in the evening and have some with bread, pickles etc wine / beer / baileys on the go.
Christmas morning - early, opening presents coffee / mince pies / biscuits
11am - full cooked breakfast x 5 people with prosecco / bucks fizz
afternoon - drinks, nibbles, coffee / cake, snacks
Dinner 7pm, full christmas dinner with wine
26th
turkey sandwiches / coffee / trifle (traditional breakfast!)
cold meat and salad / bread for lunch
party food later in the evening with wine /beer / bubbles / baileys
We cater for 25 on NYD and shop and budget separately for that !
