I know this is a teeny tiny question amd real 'first world problem' but our 90 mins drinks reception is outside and we have to have plastic glasses. We have 65 guests - around 10 ish are children. We're putting transport on to the reception after this and 50 ish of the guests have said yes to transport and so presumably there's a large proportion planning on drinking. The question... how many champagne glasses v tumblers would you buy?! Would you just buy one each plus a few? Or allow for a few fresh glasses per guest? We're also having purees so people can pimp up their prosecco so I guess it's possibly people might want a fresh glass to try different flavours?
