Since Disney doe not own SoG I am guessing you are right. If DoD was willing to foot the bill for a bridge sure, but my guess is they are not at this moment. While we want to say this is a callous move on Disney's part, I don't think it has any motivations other than the progress of a larger road making it more dangerous to offer walking as an option. I actually think we should sometimes remember how cool it is there is this option for Military considering I don't think there are many(any?) other theme resorts that offer such prime real estate for military personnel to stay in. For instance, I don't think there is a 4 star hotel in all of Manhattan that is offered for military personnel, hmm makes me wonder why a certain real estate mogul that lives there hasn't opened one? Oh wait I don't have to wonder why at all lol.
