Hi everyone, i'm just working out what drinks i'll be supplying, this is my plan-sparkling wine on arrival, then a bottle of red and white on each table(and a jug of orange per table)Then sparkling wine for the toast. We're having round tables of between 8-10 so i was going to buy 8 spare bottles in case it goes, but do you think that's enough and how do i know if people will drink more white or red??? Thanks for you opinions
