Disney World hotel guests used to all have access to Extra Magic Hours in the theme parks, but that perk was discontinued when the parks shut down for the global pandemic.
However, Disney did introduce Early Theme Park Entry and Extended Evening Hours for hotel guests, but they work a bit differently. Early Theme Park Entry is for all Disney hotel guests, while Extended Evening Hours are only for guests staying at a Deluxe or Deluxe Villa Resort. Extended Evening Hours have been happening regularly at EPCOT and Magic Kingdom, but now, you can enjoy them at another park for the first time!
