It's definitely not a stupid question and I think the problem is that really noone knows all the answers with these new tickets and how old ones will work etc. Is it worth asking whoever you booked with what you are going to get? I know the Hoppers (if you already have them) are still valid but if your ticket company have not yet bought the tickets on your behalf I don't think they physically can now??
I'd probably ring and ask to set my mind at rest.
Sorry, not very helpful!
