Hammond was attempting to create a high tech zoo, and what does every zoo have? Viewing galleries, platforms, or something similar. They weren't planned for the initial opening of the park, but it's guaranteed that they would have eventually been incorporated somewhere.I personally think it would be weird to have viewing platforms, when the Park is made for driving around. Not being on foot.
Another thing I don't understand being excluded from JP era is wide versions of the various paths, I know transportation isn't a concern anymore but seeing a ton of guests packed side by side on a tiny narrow path just doesn't look right.
