We love trail's end dinner, it's a good value for the price. Of course, it's always subject to change, but they did have basic things--like individual salad items--a lot of buffets have premixed salads on their salad bar, but they had baby carrots, sliced cukes--things my son would actually eat! Good, plain mashed potatoes and chicken(fried)...once when I was there they had plain white rice and the other time it was a seasoned rice. Simple green beans...I really liked it. I'm sure you could always speak to the chef too if you have a picky eater--they do a pasta dish, you could always ask for some plain noodles or whatever...but I see you don't have picky eaters...the desserts were not super-impressive, but I'm usually too full anyway!
There is a petting zoo there, you can take a "hayride", watch Wishes from the beach, haven't done the Campfire, but it is def. on my list!
