I always refrigerate my cakes – even those that are fondant covered. Once you remove the cakefrom the fridge, the fondant will “sweat” for a little while while it acclimates to the new temperature – but after half-hour/1 hour, it will dry out completely. The only advice I give is to keep from touching the cake while it’s “sweating” because it will leave a mark.
