My family has been there twice for dinner and we enjoyed it. Granted, it's nothing particularly unique or spectacular, nor does any of it appear to have been made from scratch. Each item tastes exactly like a "boxed" Thanksgiving dinner with Stove Top stuffing, Stouffer's mac & cheese, canned cranberry sauce, frozen green beans, etc... but a lot of families, including mine, enjoy those items just as much as the homemade-from-scratch counterparts that we have for our "real" Thanksgiving at home. Stove Top and Stouffer's may be looked-down-upon by those foodies who shun processed foods, but they are popular for a reason, especially with children, which makes LTT an especially good choice for families.
As for the characters being gone, I am one of those in the minority who finds a meal more enjoyable WITHOUT characters, who by their presence seem to double the price of the meal, double the time it takes to eat while you wait for them to circulate, and generally create a chaotic tornado of noise, camera flashes, and surplus children running between tables.
