When Disney sends an email for LLs you booked, is it broken down by the day? Also, will it reflect, for MK for example, that you purchased the LLMP and Dwarfs and Tron with individual fees?
But don't panic if you don't get any email verifying the purchase. This has happened to me more than once. As long as the LLs show up on MDE, you're fine.
And, yes, it's very annoying if there's no confirmation email. But it's not fatal.
