For most of the year the Fantasmic Dinner Package reservation time ends around 5 PM. Sometimes in midsummer when the sunset is late and the first Fantasmic show is at 9 PM there might be some reservations around 6 PM. However, the last reservations on any given day are usually the first to be booked so if there are no times after 4 PM, most likely they have already been taken. You could try booking the Fantasmic package for lunch and having a snack or QS in the evening. You can also subscribe to the cancellation thread for your month that is stickied at the top of this board. Even if there is availability for a regular dinner reservation at 6 PM, you have to book the Fantasmic Dinner Package if you want the voucher for the show.
