Disneyland's 50th is easily my favorite for the smaller things it did. Yea the headliners like Space Mountain 2.0 and Remember...Dreams Come True were awesome, but I absolutely ADORE stuff like the mosiacs, the golden vehicles, the 50 golden hidden mickeys, the Class of 1955 dedications for the opening day attractions. Not to derail
@mickeyfan5534 and his vision for this project, but when I think of anniversaries I don't really think of show-stopping parades and jaw-dropping entertainment. I more think of the small things that get added to enhance the overall park experience and make it extra special.
Then again, maybe this is just me speaking as someone who will marathon Big Thunder or something during the parade/fireworks pretty much every single time, so take that for what you will
