I'm in the "leave it alone" camp when it comes to misspelling, unless it affects the meaning. A while back someone asked if he or she could be "glutton free" (most likely meaning gluten-free) at Disney. Someone finally posted something along the lines that going gluten-free is possible, but attempting to be glutton-free would probably lead to a sad experience.
That's precisely the point. It DOES affect the meaning. When someone asks, "Is the ROL dinning package worth it?", my answer is no. If you are looking for dinning, you are better off booking a fireworks dessert party which will, inevitably, be louder than ROL. If someone asks, "Is the ROL dining package worth it?", my answer is yes! If you are going to eat at that restaurant anyway and you don't want to wait standby or use a FP+ on the show, book the ROL DINING package!
