How can I apply Disney Reward points toward a vacation that is several years out?

I have a Chase Disney Rewards credit card and some of my accumulated points are beginning to expire. Our family will likely not visit Disney for another 3 or 4 years. Are there any reward purchases that I can make with the points that would still be useful that far in advance?

The No Expire option on park tickets seems to be the only viable option for buying years in advance, but the price premium is (understandably) high compared to regular tickets and, since I have to redeem reward points, I don't believe I have the option of going through discount brokers like Undercover Tourist.

The Disney Rewards cards seem like the most reasonable way of extracting value, but they have an expiration date and I'm unclear on whether redeeming points for a Dream card starts a new 60-month expiration clock or if it is still tied to the original date that the point were earned. Regardless, the site stated that only two Dream cards could be active at once, which would make it difficult to convert all of the reward points into a spendable form.

Perhaps converting the Disney points to hotel points and applying them to an on-site hotel is the way to go? Any strategies are welcome.
