I hope this doesn't sound too stupid, but will floating candles be okay for almost a day & 1/2 in water??? We will be decorating our venue the afternoon before the wedding. We have floating candles as a part of our centerpieces. So, if we fill the vases & put the candles in, they'll be sitting in water for about 24 hours before they're even lit. Then they'll be lit during our ceremony & should burn for about 5 hours. Is that too long for them to be in water?
