after you get out of the lobby, go to the corner of you and use your dowsing map
if u use the dowsing app u should see a item it's the suit key
Go to the main desk in that area (not inside, just outside) then use the Dowsing machine. Then stand in front of the hidden item and press A. The girl will thank you, go inside and give you a Lava Cookie
If you are thinking the one where the blond lady is standing in front of her suite than you just have to find her key. And where is the key? When you get to the reception (DON'T go inside) there are stairs at the left. Go in front of them then turn to the receptionist and press A. Talk to the lady again she will go in and you go after her. If you talk to her she will give you something I don't remember what. Hope that helps.
you will need the hidden items poketch app (sorry forgot the app name) go above the hotel grand lake use the poketch app a few times tell there is a dot than press A until it says your name found the suite key your name put the suite key in the key items pocket than talk to the lady she will go in the house go in the house for a reward she will give you a lava cookie which cures a Pokemon that has any status problem/condition
You have to use the detector app outside the hotel. It took me ages to find it and at first i thought it was going to be an unexplained mystery but you can find it.
It is super close to the suite!!!!!!!!!!!!!!!!!!!!! In fact don't even go up the stairs if you do you've gone too fare!!!!!!!!!!!!!!! If you have a Pokemon watch then it should take you only 5 to 10 Min's to find it.!!!!! If you don't have a Pokemon watch then it might take you 5,10, or even 15 Min's to find it!!!!!PS. When using the Pokemon watch........ You are going to want to use the Item finder. The item finder is # 7 on your Pokemon watch!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I hope I Have helped you!!!!!If you have any QUESTIONS Email me at asides1993@yahoo.comSincerely - MichaelWere is the suite key in Pokemon diamond?smilelily:that didnt werk
use the dowsing machine near the suite
The Suite Key is northwest in front of the entrance to the beach of Route 213. You will need to use the Dowsing Machine Poketch App to find it.

use the dousing app. around the lobby
Truly I dont think you can get it in Diamond or Pearl version sorry.
You give it to the girl who is locked out of her cabin. She will give you lava cookies
The key is somewhere just past the south entrance hidden on the floor so use the itemfinder to find it.
you have to go in front of the actual hotel building a couple steps in front of it with the item finder app and dont stand on top of it and press a.
Use your dowsing machine around Lake valor and you should find it neartwo homes
As far as I know, you can get a Lava Cookie from the lady who is looking for her Suite Key, near the east of Pastoria City.
