So I purchased a Groupon to get personalized M&Ms for our wedding favors, but I'm worried about how early I should order them and whether they'll melt before the wedding. I'm not concerned about the day of - I'm concerned about storing them for weeks before the wedding. I live in an apartment without air conditioning and it can get very hot. We have A/C in the living room only but we don't run it 24/7 because it's too expensive.
I've read not to put M&Ms in the fridge because the condensation will make the colors run. Should we just keep them in a dark closet or something hoping they stay cool enough and fill the favor boxes the weekend of the wedding? Will that be cool enough?
