We did concierge last December. We were there two nights and it was awesome. Here is what they had:
Breakfast: cereal, juice, milk, fruit tray, pastries, some kind of hot item (I can't remember), oatmeal, soda, water, hot tea, coffee
Tea Time: Mickey shaped scones that were delicious, chocolate covered strawberries, mini sandwiches, and drinks
Cheese/ wine time: cheese trays, wine or beer, fruit, soda
Dessert: umm, mini desserts, milk and cookies.
The sodas are in glass bottles but there are carry to the park cups for them. I know there was more but I can't remember. The lounge also had story time, games and a viewing area for the fireworks.
Hope this helps.
