This hotel in Riverside, CA, the Mission Inn. Only ever been inside once, since it’s crazy expensive to get a room and someone I knew was staying there. There’s tons of cool architecture and winding, sprawling grounds. My favorite is all the spiral staircases, some that are seemingly randomly placed. Reminds me of the Winchester Mansion with all the variation in building. If you’re in the area, I highly recommend checking it out even though it’s not abandoned. Might just be able to sneak past the front desk if you’re confident enough (or if it’s busy enough to provide cover
)
