These aren't mods to the HTT, but are some projects I made for our last trip to Fort Wilderness at Disney World (we still had the Cub then).
This is a street lamp made from a Christmas tree stand, 3" PVC pipe, some couplers and acrylic globes glued together to look like a Mickey head. I also have a plain round globe that we use most of the time.

These are Mickey head awning lights that I made too. The heads are acrylic globes and the ears are plastic baseballs. We use these most of the time that we camp, but occasionally swap them out for some windsock-type lights that we have also.
