Not sure whether to ask here or in camping! I'd like to serve ice cream at a birthday party, but it's at a venue with no fridge. Would need to keep it cold for about 2-3 hours I guess. Would a coolbox do it? (I love an excuse to buy something new
). There is electricity so could get a plug in one if better. Not interested in dry ice due to faff factor and presence of many small children
TIA
