Where is the key to the closed hotel at Lake Courage?

you press a

Mais il est où l'hôtel ?

you press A

I use the radar but I can't find the key, help me pleaaaase!

ou

could you connect to the ds with me please

You just need to go to the girl's room, go left until you hit a wall, take a step back, and look at the bush. Press """a''' and you have the key, it's magic :)

What are you talking about??? You have to press A and L, it's called the room key, not the secret key!

Well no, it's not the poke radar that's in your bag, it's a pokemontre software!! It looks like a radar and if you press on it, it makes circles. So look around the hotel (not further) and you should find it very quickly. I hope you'll find it ;)

Thank you, but do we have to use the Explorakit?

Hi, no, you don't need the explorakit, you have to go towards the hotel at the bottom, set the radar to L+R button on the bottom left

and there you go

I hope I helped you.

ANYWAY!! WHEN YOU DON'T KNOW, DON'T SAY ANYTHING!!! HEY POTATO!
You shouldn't press L+R...
I'm going to explain everything to you, it's simple you'll see... so the thing is... you see the Courage Lake shore? Well, you go to the reception, go out the back, turn left but without making any fuss. Then you have to take out your item search Pokégear. You know, the one that looks like a radar, where you touch the screen and it makes circles, and sometimes there are little dots that appear (that's when you find items). Anyway, I was saying, you bring it out, and normally when you touch your radar to the left, don't touch anything else and the radar will keep making circles without us asking it anything. That means you can press A! Then there will be the room key of that blonde who misplaced it like a total airhead. She’ll say something like, "Oh yeah thanks that's nice." Anyway, very brief thanks…. So then she goes home after having fasted since you started your game... Go see her... And she gives you a cookie. A cookie.
No! I'm not joking, I just did it, it works on Pearl and Diamond. This blonde chick is really stingy, who does she think she is giving cookies to people who helped her avoid starving at her doorstep! Anyway, I hope I was helpful!

P.S: Message to those who say nonsense without knowing if there's any truth behind it: You can still check your solutions before posting them online!

No hard feelings, Zelda.

Thank you very much!

As soon as it starts flashing, what should we do?
