Probably somebody from reception pick up the package when arrived(signed it too)

No doubt they would've used their real signature, so that puts an end to the DNA.

So its a win for me right?

No, it's a loss.
If the clerk at the front desk signed using his authentic signature, then the investigation will lead to him. And, once questioned, he'll tell the police he handed the parcel to you.
Moreover, you said there's a camera in the area. So what, wanna try and dispute the fact of him handing you the parcel, making him a thief? Really? I don't think so.
