The location of this Mystery Cache is VIRTUAL. It’s not here. It’s not in the Humble Reservoir. Solve the puzzle below to discover where the cache is hiding.
🏩 BREA BOULEVARD HOTEL 🏨Â
It’s rare to find a hotel with a real room key to open your door. You’ll find proof of that when you check into this "hotel."

Below is an empty list of the world’s top ten hotel groups in 2024 (not in order). Just fill them in and gather up the first letter of each line. Put that string of ten letters into the Certitude checker and you’ll have the key to this hotel! To help you, there’s one letter from each hotel group already in place. Two of the final ten letters are already provided as well. How hard can this be?
