For almost every large event at this point, it will be important to be able to arrange for internet services. WiFi is simply expected, and no event will be complete without making an internet connection available. While there may be several convention center internet providers available, including the venues themselves, the best option is Trade Show Internet.
They have internet services coast to coast in major cities. Because all of their technology is portable, it is easier to upgrade than the venue solutions. The kind of hard-wired technology that venue facilities install may only be as up-to-date as when it was installed. Trade Show Internet is better able to make sure that their technology is constantly upgraded.
They will often also be less expensive. Venue options are often the default for many planners, and so they can charge more than the technology they provide is actually worth. Rental means you pay less for better technology.
