I'm somewhat amused by the tweet about Garden Walk not wanting to sell. One, that means Disney likely reached out to more than just them about selling. I wonder who else they talked to? Two, I'm not necessarily sure how a Garden Walk purchase benefits them other than parking. If that's the only parcel you've picked up and you build over Toy Story lot, I don't see any theme park expansion there because you'd be awkwardly bridging a huge road with a super wide bridge, so the only logical thought is parking.
Ultimately I would love to see them pick up a few properties, build a a California Adventure sized third gate and get some new unique attractions in there.
