Another big empty spot on the map and they could do another show and sell treats there and do merchandising. If Walt were alive and running DLR he would be turning every empty spot into active spots that can be used for tie ins and merchandise/food sales. Matterhorn is tied to Third Man on the Mountain which was a Disney movie. I miss the dinner show so much. Do like the blue bayou and charge $30 for an all you can eat Polynesian dinner like Celebration Barbecue. You set down and they serve you gluten free and regular hawaian bread then out comes salad and side dishes like Ariels then teriyaki chicken, hawaiian style ribs, tofu and veggie plate, and then gluten/soy free desserts and a slab of coconut sorbet for everyone else. Ohana goes west would be fun, bring there menu out here.
I think if they bring something back it will be CMs which is cheap enough, a few props, and maybe even redecorate the place a touch. Cheap to start up and not much to run and merchandising is possible.
