As for why I think that Gulliver's Gate failed, here's my thoughts:
1. The name was about the level of most people to understand. Many times I was asked what did the name mean. They couldn't recall or connect the idea of Gulliver's Travels to the idea of a miniature world. If the name was something like "Gulliver's Gate Miniature Land" people might have had some idea about what it was about;
2. Poor publicity didn't help. Other than a few spots on some television programs, some articles in a few magazines, a single ad in the June 2017 issue of Model Railroader magazine, and two tourist buses with Gulliver's Gate pictures and name, there wasn't any other publicity. If a person missed the TV shows or magazine articles, or wasn't on the route the buses took, how else were they going to hear about it? Apparently the attitude of management was that they were only interested in attracting tourists, not locals. As a result there were no posters on the city buses, subways, commuter trains, or billboards. (They did finally start putting posters on the trains in July 2018...too little too late.). Management felt that tourists didn't take mass transit;
3. Ticket prices. Many guests and potential guest complained about how high the tickets were. GG did offer discounts, if you knew where to look (such as Groupon). The problem of course is that the location near Times Square commands a high rent, hence the ticket prices;
4. The front of the building at street level didn't make it clear what Gulliver's Gate was. Other then a TV screen with some videos, and some of the Washington DC buildings on display there was nothing to really inspire a passerby to come in. Also, some people had trouble finding the entrance as well;
5. Crowd control. At first they never considered how to keep traffic moving during popular days, like weekends and holidays. As a result the place would become constipated with people. Meanwhile, there would be people waiting outside who couldn't come in, even though they prepaid for tickets at a certain time. Also, once a guest left the building they weren't permitted back inside, even if it was for a few minutes. Which leads us to;
6. Food and drinks were not permitted inside the building. The obvious reason was to keep the displays clean. The problem was that the guests would get hungry and/or thirsty. Because they weren't allowed to leave the building to get something to eat/drink they would get annoyed. Others would disregard the rules and eat or drink anyway. There was in fact a beverage machine and snacks in the gift shop, but where were the guest supposed to consume them? Last spring I saw plans for a reorganization of the floor plan, which would have included a food court, but I doubt anything will come of it now.
