I would call and ask.
You have a non exp. ticket which from what I understand you can upgrade at any time but you will only get what you paid and then the math of how they figure it. The options as I understand have no value when doing this. Also from what I understand the AP will be back dated to the date of first use of the excahnge ticket.
most likely not worth it...
IMO keep it if an AP is useful buy it ticket prices are always going up....
5 years ago I paid 360 for a 10 day non expire park hopper with options and thought it was expensive

imagine Disney for 36 a day plus 5 water parks for free
