We go frequently to the Fort. Agree with the idea of joining or asking questions of the Fort Fiends. All types of inside info. from folks who frequent the Fort and WDW.
At our ages now, we don't necessarily want to go to the parks often. But, the Fort remains a priority camping destination for us. We refer to it as the "unDisney" component to WDW. The campground is very laid back compared to the hustle and bustle of the hotels and parks. One can actually relax while on vacation.
The cost IS expensive. You get what you pay for. Free bus transportation to anywhere on property. You are only a bus ride (or boat ride) from some of the best restaurants in the country. Highly maintained comfort stations that are cleaned multiple times a day, beautiful landscaping, and in most cases sites that are adequately separated from each other, often with shrubs providing some privacy.
There are sidewalks throughout the campground that encourage people to walk from point to point, ride bikes, or jog. There is security constantly in the Fort, both Disney and the Orange County Sheriff, patrolling the loops, so campers "feel" safe. Often, you may find joggers out early morning, or kids out after dark. You can walk from the Fort over to the Wilderness Lodge for a meal or drink, or you can take boats from the Fort to the Contemporary Hotel or Wilderness Lodge, or a boat to the Magic Kingdom.
There is much more, but I'll let you investigate further.
