Is your 7 y/o into Star Wars at all? My kiddo that age loved Jedi Training, Star Tours, meeting the characters (Chewbacca, BB-8 and Kylo Ren when we were there last week), watching the Storm Trooper march. But if there's no major Star Wars fan in your family, I agree it may not be the best use of a ticket day with no hopper. Unless you'd like to do a short day with pool time.
