It is free to resort guests. You will need to show room cards for each member of the family - it is 1 hour early in the mornings and 3 hours extra in the evenings - We tried it on our trip in May and the evening EMH was CROWDED!! We did Enights last year a loved it!! I would rather pay and have enights back with a smaller crowd then Extra Magic Hours they way they are now - it was just as crowded in the evening as it had been in the day.
