No luck for me. I bought several sets of non-expiring tickets a few years ago for our family of 4 and still have one set of non hoppers, but we always buy hoppers now. When I asked about adding hoppers last year, the best they could do was refund my tickets at original purchase price and purchase new hoppers without the discount. It was not worth it so I ended up buying new tickets.
Just looked at the numbers. I originally paid $1600 CAD for 7 day non-hoppers (4 people). To purchase the same 7 day non-hoppers now to go at Christmas, it would be $2600 USD, or for 7 day hoppers, $3000 USD. I think I will hang onto the tickets and just use it for a Christmas trip in the future.
