I know that this thread was from last year, but just wanted to add in case anyone else was looking: a few years ago we stayed with two teenagers (son and daughter) at the Poly Club Level. Hands down a great decision for us.
There were three beds, the extra room of the lounge was fantastic to have, ease of use for all of us to walk to the TTC, take the Monorail or the shuttle boat was great, and it was so hot in August that the breakfast/evening apps/beer/drinks were almost enough for our appetites. Our son "won" a lake "racer boat" half an hour, when at a pool contest, and he and our daughter would want to sleep in while my husband and I visited some of the parks early.
It was also somewhat romantic for my husband and myself - the lounge was much quieter at breakfast than the quick service place, and there was much more privacy for all. While we could have just brought snacks with us, at the time because of a special Disney was having, the cost of 2 beers per adult, plus breakfast, plus snack, plus appetizers (we went to two "fancy" restaurants, and a couple of counter service places over 5 days) was definitely a wash - we most likely would not have ordered 2 beers a person, but would have headed over to Trader Sam's and dropped even more money on just one drink a person. Also, my son ate a lot. He was a teenager. He LOVED having all the food choices there.
With teens, if you are not splurging for two bedrooms, I feel like club level is a really good value, especially at the Poly because of ease of transportation for everybody.
