Heritage Museums and Gardens Pass

Hi. Please be sure to tell patrons that they can't use it for the current Christmas lights display-the pass is only good "in season". It's too bad, because a patron just returned it, having been told by the museum that she couldn't use it. She was gracious about it, but we want to make sure it doesn't happen again, because it certainly isn't an obvious point (the pass itself says "not valid on special event days", but that's not precisely the same thing). Thanks!
