I find it difficult to believe that orchids are in a position to "fritter away" excess
sugar.
To paraphrase a common _expression_ 'guttation happens', the plant has no control over the environmental conditions that cause guttation ie; high soil/media moisture and low transpiration due to high humidity and no air movement. The grower however does have some control over these. Orchids in general love high humidity but most hate the no air movement part, so keep those fans blowing even at night.
