We always spend some time at FW during our trips too! It's fun. Try the canoes - they are a blast. Also the campfire singalong is great.
To check what time EWP comes through, you'll need to have your dates in mind because depending on the time of year it will vary. You can get that info when you check into your Disney resort. We took the hayride a couple of years ago and it was so fun. The driver took us to the lake and we watched the EWP. Very special. I think we paid $8 each. You can take a private carriage ride but I think it's more like $30.
Take the trail and hike over to Wilderness Lodge -it's a fun walk.
We love Fort Wilderness. It's probably the most unexplored resort by most guests. They are really missing out.
