At least the goonies had to count their paces to get to their perfect spot because a map told them to. Rey just happens to be there . . . by convenience. Rey conveniently happens to be standing in the *one and only spot* on the Endor moon that allows her to perfectly line up the the dagger.
The whole damned movie is a string of conveniences. I know that SW movies all rely on that to some extent, but TROS is nothing *but* plot conveniences. Just think about the dagger and what the story about it ended up being. Count the conveniences:
Rey found that Sith dagger that murdered her parents when she wasn't even looking for it. And it conveniently happens to be a key to finding what she *was* looking for.
It was found because Rey and her friends conveniently crashed onto the same exact sandpit that had trapped Ochi the Sith hunter (what are the odds!?).
The dagger blade is conveniently still perfectly lined up with the outline of the DS2 wreckage (even though that wreckage would've likely changed by way of weather and oceanic elements during the 15 years since the dagger was used on Rey's parents).
She is conveniently capable of expertly navigating a sea-skimmer ship to get to the wreckage. Rey, the *desert* scavenger, was able to sail a sea-faring vessel through brutal ocean waves.
Upon arriving at the DS2 wreckage, there's a door that conveniently is still functioning after all these years. This door, btw, leads to a room that probably wouldn't even exist since the door was on the same wall as one of the windows. Just another convenience.
The wayfinder she went there to get is destroyed in the throne room wreckage by Kylo. But she takes his TIE Fighter which conveniently has the only other wayfinder in the entire galaxy.
But she burns the TIE Fighter on Ahch-To. No problem, though, since the wayfinder conveniently doesn't burn.
The wayfinder conveniently hooks up to an X-Wing that is also conveniently presented to her and ready to fly.
She uses the wayfinder to get to Palpatine and kill him. She's able to kill him (somehow) by conveniently having two Jedi lightsabers with her (which she needs to cross together . . . because that's how it works, duh!).
And that second lightsaber was only given to her moments before, on Ahch-To, because Luke had conveniently kept it in the most "unfindable place in the galaxy" . . . even though he said that Leia had wanted it to end up in someone else's hands. Convenient!
