In the second link you will see that the NathalieF states that,
"We currently do not offer any options to redeem points for Disney passes. This was offered in the past, but this offering had stopped about 4 years ago. We have definitely passed your ideas along (both in previous Forums and Ask & Answer questions, as well as this discussion) to our Ideas Team, though. Thank you for the question/suggestion!"
However, in the first link you will find a suggestion from tjcnewyork about using Marriott's Instant Redemption. You would buy the tickets from the hotel concierge, have them put on your room folio, and then use the Instant Redemption option in order to convert your points to dollar value. More information about Marriott's Instant Redemption is available here: Instant Rewards | Marriott Rewards Instant Redemption
