If hotels with exterior corridors were unsafe, we'd be hearing about it all the time. There are a great many hotels designed this way, especially in southern CA. Follow basic safety rules when staying bin any hotel, or when you are out in any public place for that matter. Lock your car, put anything that resembles a purse into the trunk or on the floor, park as close to your door as possible, park in well lit areas when possible. When you go to your room, immediately shut and latch your door. Avoid entering your room if there is anyone nearby who makes you feel suspicious (like a single person loitering around, not a family carrying a passed out kid LOL). If the person doesn't go away, go to the front desk and ask for someone to walk with you to your room. Any hotel will accommodate that request, because a crime on their property takes a hot on their business big time. Not only that, but the "Good Neighbor" hotels are approved by Disney. If something like that happened due to negligence, they would risk losing that endorsement. Avoid leaving your room at night, and if you do, stay in lit areas. When you leave ALWAYS pull the door closed and attempt to reopen it to make sure that the door is properly closed. Don't open the door for anyone unless you know who it is. When in doubt, if someone claims to be a hotel employee, call the front desk and ask if they've sent someone to your room. I have more tips but am walking out the door LOL
