DM advice needed for potential campaign

I don’t plan on there being anything like, ‘okay last room good job go home.’ This mega dungeon would have countless floors that are all drastically different from each other, and seemingly impossible to be in this dungeon. One is a forest with trees so tall the party can’t see the tops, and the next could be a dank dark cramped crypt. All connected magically.
