you will need a action Replay and use the code that makes the guy in the green appear inside a poke mart and he will give you the members pass that unlocks the door. and if it doesn't work , i don't know what happened.
The only way to open the old hotel is with a member card. Member cards can be received by attending Nintendo events and pre-ordering the game.
it is the one that won't open in canalave city.
u need a members card
You need a hotel pass that you can only get with action replay

You have to get a key to the locked hotel in Canalave city and you need a Nintendo event.And then go to the hotel and sleep in the bed and youll get a nightmare and end up at this island where dark rai is at
Go to the < of Jubilife City towards Canalave City. In the building separating Jubilife City and the Route to Canalave talk to a person. He will give you the Old Rod.
you have to go to canalave city and go in the old harbour
If you are talking about the key that allows you to get into the hotel in Canalave city, You must get it from a mystery event . A mystery event is an event held at game stores, such as Game Stop, where you can download rare Pokemon and items to your Pokemon games, such as Diamond, Pearl, Platinum, Heart Gold and Soul Silver. If you go to a mystery event and are able to get the hotel key, you open the hotel and sleep there for the night. when you wake up, you will be in Canalave city in a different time period and will be able to catch Darkrai.
You can't. The hotel is useless. Unless your talking about the one in Canalave. For that one, you have to have the pass for it.
