This is one of those "depends" questions. The food is a bit better at Trail's End, and it's less expensive, too. WCC has CM antics that might amuse you and your family while the food is average (though plentiful if you get all the all you care to eat option). So, it depends on whether you want an interactive experience such as WCC gives you (not all servers are created equal, though) or true buffet in a relaxed atmosphere. One other thing to keep in mind is from where are you traveling? If you're at MK or the Contemporary, you can boat to either the Wilderness Lodge (WCC) or Fort Wilderness (TE). If you're someplace else, then getting to FW can be a bit of a longer trek. All things being equal, as much as I prefer TE's food over WCC, I'd probably do the latter since you've never experienced it.
