We just got back from staying 7 nights at YC Concierge with 2 teen children and one 4 yr old. It was definitely worth it! Our ds at almost all his meals from the lounge. If we had not purchased the meal vouchers ahead of time, the rest of us would have eaten more there too....it really is plenty for us and because we only spend a few hours at the parks at a time and go back & forth throughout the day, it's great for us.
For Breakfast it saves a lot of time just going to the lounge on the way out or for the older kids to be able to sleep later then go down and get something when they are ready. During the day 11:30-4:30 they always had mac & cheese (mickey ones) and pb & jelly sandwiches, chips, crackers, popcorn, cheese & crackers, plus sometimes a dessert. In the early evening (dinner hour) there was always a hot dish that came from Yachtman Steakhouse or the Beach Club Cape May restraunt. It ranged from salmon, barbecued steak, or a seafood pasta dish, they also had mac & cheese and pb & jelly sandwiches at this time, with crackers & cheese, assorted olives/mushrooms, veggies, fruits, and it varied every night. There were lots of choices of wines and you can ask for beer. Later 8-10, always the same cookies, a dessert (cake or cheese cake), drinks to make yourselves (whiskey, baileys, kalua & such).
Also, a note and not everyone know this, you can ask for milk, choc milk, hot choc, juice boxes, water bottles (large glass) anytime during they day and the conciege folks will get it for you from their kitchen (just a few steps down the hall from the lounge). Sodas (sprite, coke, diet coke, gingerale) are kept in the rightside cupboard below where they keep the old drinks all day long. We always got 2 water bottles every evening to last us til morning.
