Hi Piglet1234,
We stayed on the 14th floor in January. From what I can remember they serve a continental breakfast until 10:00am. It usually consisted of bagels, muffins, bread, fruit, donuts, pastries, cereal and milk. And there was coffee, decaf, tea, and juice. They also had a toaster there if you prefer your bread toasted. After that they put out light snacks which usually consisted of potato chips, popcorn, and cookies plus drinks. I can't remember what time they served that until. After that they had what they called afternoon tea but I honestly don't remember it being any different than the light snacks. Around 5:00pm or 6:00pm they put out hors' devors (did I spell that right). It was usually some type of meat, fish, or chicken dish. They also had cheese and crackers, veggies and dip, peanut butter and jelly sandwiches for the kids, and finger foods. We were pretty full from that. Then in the late evening they served dessert, coffee, tea, and liquers until 10:00pm. The desserts were to die for!
I will tell you this, the food used to be supplied by the California Grill but the concierge staff told us when we arrived that it was now being furnished by the Concourse Steakhouse. Also, they said that the dessert variety was discontinued but they would put out a cake. However, I was puzzled by that because the whole time we were there they did continue to have the variety of pastries in addition to the cake.
I think you could probably skip buying breakfast the whole time you're there. You might be able to skip a couple of dinners.
As far as the 14th floor as a whole, it was nice but I've stayed there 3 times now and each trip I've seen it decline a little bit more each time. The balconies are larger than standard rooms plus you have the advantage of using the balconies at the concierge lounge. They overlook the Magic Kingdom so even if you don't get a MK view you'll still be able to use the concierge lounge balcony. The bathrooms are much larger but I think the bedroom part of the room is slightly smaller than the regular rooms to make up for the larger balcony and bathroom. Evening turn down service comes standard with the price of the room. They also have check-in on the 14th floor so you don't have to stand in line downstairs. You'll also have a VCR and a refrigerator stocked daily with soda and water. That's about all I can remember. Hope that info helps.
