We've done concierge at DLH and PPH. You pay by room, and if you stay in a suite, it counts as one room, regardless of number of bedrooms or number of guests. So, for a large family like ours (six of us, and past trips we have had up to 8) it is totally worth it. The four adults are all coffee drinkers and it keeps us from having to bring our own coffee pot (although, we may bring it anyhow), which is huge for us. Also, my dad eats fruit for breakfast every day, so he can just eat in the club. My picky kids all eat bagels and cereal, so they're taken care of too. We get bottles of water and yogurt and juice boxes and head to the parks. It is great!
We also utilize the afternoon/evening snacks just about every day. They aren't anything extravagant, but they work for us.
They loan out movies (we usually watch one per day, too much else going on to watch more than that) and have the paper and coloring things also. It really is quite nice.
