I have booked into the hotel for 2 days, Wed 25th to Fri 27th, does the hotel have discount tickets for the Universal Parks

You can buy tickets at the hotel. As far as discounts nothing special from the hotel itself. You do get early to Volcano Bay and Harry Potter in the Universal Studios park. If you're a Florida resident, which this is what I did last week. I bought, online, the BOGO tix. I got 1 day free with a purchase for 1 day (both parks).

No discounts

they sold the tickets but they dont have discounts for nothing.
