Gold Digger - Dead Island Sidequests Walkthrough
You get this quest outside the hotel lobby area.
To get to the hotel, travel towards the big building in the horizon (you cant miss it). Or you can set your quest tracker to track the Born to Be wild quest from Sinamoi. That quest takes you to the hotel parking lot in the same area.
Once you reach the main hotel building, locate the lobby entrance. The lobby doors will be locked, but near the door sits a body with a lootable item near it. Pick up the item, the hotel bungalow 14 key.
Follow the directions in the radar to get to Bungalow 14. There will be loads of zombie opposition along the way. You can fight them if you feel like it, or just sprint through them.
Once you reach and enter bungalow 14 the quest will be completed.
Make sure to loot all the stuff in the room including cash and an ID card. Locate the painting on the wall, there will be a safe behind it with a nice amount of money, make sure to loot that too.
