Hello:
We loved the concierge stay for the food offerings. Now i think it depends on how many are in your party whether financially it is better, we had four. It also may just make things easier.
Because of the heat we used the concierge for two meals breakfast and dinner. As I said we ate lunch elsewhere, but ate light at dinner time.
At the dinner hour they had penne, chicken wings, chicken lo mein, tacos and sushi (there were turkey/swiss sandwiches on sushi night as well on the kids table, which adults are able to eat from) these were all on different nights as well as those they would have a huge bowl of cut up mixed fruits, a vege platter, a pickled peppers and olive platter, cheese/crackers, and a huge bowl of strawberries on the kids table with some sort of sandwich uncrustables peanut butter/jelly, tuna and turkey/swiss, a big bowl of pudding one night. I did not gain a pound on this trip. lol
There were also oranges, apples, pears and bananas and fresh baked cookies, sugar, oatmeal/raisin, and peanut butter and drinks, try the guava juice and a huge bin with different pop, bottled water coffee/tea. Wine in the evening.
We took the difference in price between room only at the poly and concierge gv and for us it was about 55.00 more a night for the concierge service. Then I subtracted another l0.00 for the fridge in our room as I would have had to pay for it if I were in room only cause it is included in concierge rooms, so then it made concierge 45.00 more than room only and I divided it between 4 people and it worked out to 12.50 more a day for each person.
At that rate it sure was worth it for us, the staff was wonderful in the concierge lounge as well as the view of magic kingdom. We really enjoyed our stay there. I think it depends upon how much more a night it is over room only if you are thinking of your pocketbook.
Have fun,
Deb.
