if you can plan your time so can see Haunted Mansion Holiday. Even though I'm in Camp Against It you don't want to miss it. Other than that I'd say go slow and don't rush there's so many little details
I miss the old show we use see to as kids here at the Disneyland Golden Horseshoe, the place never felt the same after it ended. It still doesn't feel the same 30 years later without it
