I know this sounds crazy, but it is what I do as a last alternative... I always have my car with me, and my deductible is only $100.. sometimes I will store my laptop in the back area of my suv, in it's case with towels or a blanket from my home thrown over it while I am at the parks. If it were to get taken from my car, at least I will be covered through my auto-insurance! If it gets stolen from the room.. good luck trying to recover anything from Disney... You just don't place it back there, then leave it... you have to place it back there, and go to where you were going.. so no one has actually seen what you have placed back there, you never know who cases the parking lots. Sure Disney has "security" at the resorts, but what does it take to get into their parking lot? Show your DL that is it.. or even take the bus from Down Town Disney...
Many seem to forget it really is easy to access these resorts....
Disney really needs to update their safe's.. and become more tech friendly!
