My family and I just returned from the Grand Floridian a week ago, and we ate at the Grand Floridian Cafe one night during our stay. We actually found the meal to be one of the highlights of our trip. We went for dinner, so I can't comment on the lunch entrees, but we were all extremely impressed with our meals. The atmosphere was very pleasent and relaxing, and the service was excellent! I'm not sure how long the wonderland tea party lasts, so I can't help you on the timing aspect, but if you have time I would highly reccomend grabbing lunch and soaking in the relaxing atmosphere of the Grand Floridian Cafe. Enjoy!
