D23 has no soulfulness. I was a founding member, defended it in these forums against its critics. The events were mostly in California, the really good events sold out immediately and over time the face of D23, Steven Clark disappeared and was not replaced and the quarterly gifts stopped. The year that the 4th quarter gift - historically a replica of a Christmas card Walt Disney had sent - was a discount coupon for skin care product, I decided to non-renew.
I read the reviews of D23 events at WDW and they always included an element of disappointment. Myself, I attended a Fanniversery event in Atlanta and had mixed feelings about the experience.
My recommendation, support the Walt Disney Family Museum instead. Unless you want to take a Disney Studios tour - you'll need to be a D23 member to do that. But to feel a connection to the Walt Disney part of the history- the museum in San Francisco is a good choice.
