stayed POLY concierge unexpectedly from Spet 18-25, 2007 (just a few weeks back, we had booked GV, requesting Tokelou but were upgraded to Hawaii, truthfully I missed the extra space but the CL made up for that)
We loved the lounge for everything from awesome view to delicious food.
We also are a party of 6 (one under 3years) so this may make my take on it different from others. As you are quite familiar with that number, I won't bore you, just say when you are feeding/watering

a family of 6 it adds up quickly!
We never purchased a drink the entire 8 days we were there! Now we were on
DDP but still, this is usually a budgeted item for us of around $100+easy and we often go over! The lounge always always had anything and everything you could want for kids from water bottles, to juice, soda, hot chocolate, milk (just ask, they will bring it out for you) and even mixed punches (non-alchoholic). Adult selection included beer, wine, mixed alcoholic drinks, and water, tea, sodas, again, just ask, they will probably have it. We couldn't get over the fact that it was all just available when we needed it. Can't speak much for beer/wine etc. as we don't drink those.
Morning continental breakfast was mostly breads I think altho I only went to lounge myself once. other days my DH brought it back to room for me. The Haiwain bread is yummy. Always cheese danish. Always fresh fruit and it was so good. Bagels and cream cheese. toaster available.
Although they do not serve lunch, there are always snacks out in afternoon. Popcorn, goldfish, really good chips and salsa, mixed nuts, soft baked cookies,usually 3 varieties, gummy sharks (my DD3's fav!). . .probably forgeting a few things.
Dinner is considered appetizers only. They have a different menu for each evening. I confess, we made this dinner at least twice for our 8 day trip! It was just so so good and convenient! There is a thread on here where someone scanned in the menu they give you at check in. . .I can't possiblly remember it all. My favorite were the lettuce wraps and turkey kabobs. they had pork and wings and so much more on other nights. Everything tasted so fresh and was replenished repeatedly during all hours they were open while we were there.
Desserts. oh my. and stuff for the little ones as well. 'nuf said. My DH asked me repeatedly if I was sure we would be to large a party to return for next year (Our DD turns 3). At approximately $100 more a night for CL, he thought for our family of 6 it was a bargain!! This from the man who is never happy to pay anything extra if he doesn't need to!
What did I forget? Ask away. We had a great time enjoying CL! Oh, DD12, DS4 and DD2 thought the tiny furniture and tv tuned to Disney channel were the best. DS15 just enjoyed the soda it seemed!
