Yes, you absolutely can. But, you can only unload from the front of the building. The hand-carry policy is spelled out in the Set Up Manual. There are specifications about acceptable equipment you can use to cart in your items, as well as about the size of the vehicle that you are unloading. Please know that an attendant must remain with the vehicle at all times to avoid ticketing. Also, be advised that you must wear your exhibitor badge or have a work pass in order to access the exhibit floor. You can retrieve these at registration, which is set up in the lobby where you unload your products.
