I don't think Klein Matterhorn (Matterhorn Glacier Paradise) is closed according to this timetable www.matterhornparadise .ch/download/fahrplan-pdf_download_7499 and see post from Alpenrose666 on this thread www.myswissalps.com/fo rum/topic/early-may-trip-itinerary-advice.
But even if it is Gornergrat (www.myswissalps.com/go rnergrat) will still be running.
