So did I!
Though I recall that it had been a bit chilly on a couple of recent F&G opening days. I remember that the poor butterflies weren't moving too much. Perhaps Disney delayed a bit hoping for a warmer opening. Last year there was a late cold snap the really touched a number of the F&G plantings. As a northern gardener I know how tough it is to keep all of those flowering plants looking good.
Stop in on your last day, you might see a few of the topiaries and plantings.
