Angel:
You've just listed several "gems" at Disney that don't cost you a thing, but certainly create memorable experiences for the whole family, regardless of whether you're a resort guest or not!
One of our family's favorite activities is Chip 'n' Dale's Campfire Singalong. It's the one time I can sing out loud and my kids aren't embarrassed! Best of all, it's free and open to any guest. You can get to
Fort Wilderness by taking the last car lane to the right through the Magic Kingdom gate. Non-resort guests park in the outer parking lot and take an internal bus (I recommend the Settlement Yellow Line to the 1500 Loop stop). After the campfire, consider walking down to the fort's pier for the water pageant at 9:40 p.m. and the Magic Kingdom fireworks!
All of the ferry boats and of course, the monorail, are also free. These are rides to themselves according to my boys. Because our family typically will visit Fort Wilderness
without going to the theme parks, I recommend making a full day of your fort visit. Rent a canoe or bike; take a tour of the stables; order a bucket of take-out chicken from Trail's End and if you need to kill time before the campfire, take one of the ferry boats on a round-trip ride over to Magic Kingdom or The Contemporary and Wilderness Lodge for a self-tour!
Wishing y'all a magical vacation!
