To be frank, I don't know that it will make much of a difference. I haven't personally felt the impact of any particular leadership at
Disneyland - I haven't felt that it's been different in recent years between D'Amaro and Campbell, but I've had issues with how Disneyland has been run between both of them. Refurbishments are few and far between, and I feel like many attractions and the parks as a whole have suffered for it. Also, the cast members - cost of living is significantly higher out here than Florida, and I believe cast members receive about the same pay - and it seems like most cast members at DLR see it as just a job, not a fun opportunity (as with so many DCP students in WDW) and customer service suffers a bit as well when compared to WDW.
Overall, though, the entire resort has never really been more successful. So perhaps they're just doing a lot of things that I don't see but others really care about.
