I just did a quick glance and it looks like it’s about $20pp ish for those extra 15 years. You break even if you rent the points out for 2-years at some point between now and expiration.
Value here probably comes down a lot to demographics and how important the ability to exit the contract is.
One is guaranteed to be worth $0 in 17 years… the extended will probably decline gradually to $50-60pp in today’s dollars over that period of time.
Given that all of the other 2042 resorts will have their
point charts reset, it will probably make OKW an even greater value for people in 2042+ than it is today.
But none of that matters if you are of the age where you don’t think you’ll be traveling to WDW in 17 years and don’t care about the ability to sell it…. or just want to pay the lowest out of pocket upfront.
To each their own.
