Club level at the Swan (and Dolphin) is different than concierge at other Disney deluxe hotels. CL has continental breakfast offerings from 7-10; then the lounge closes until 5. Then there are appetizers from 5-7 and the lounge closes at 8. Soda, water, coffee is available for free, beer and wine in the evening at a reduced price (I think 2.75 for beer and 4.00 for wine). The difference in price is about $50 per night. (If you are a member of the Starwood Preffered Guest program, you can get it for 1000 points per night. Also, I think gold status members can request a complimentary upgrade. You can earn Starwood points a variety of ways - there is a whole thread on that alone.) The views from the CL floors (11 & 12 for the Swan) are great, but there are no balconies (except for some very large and expensive suites that are there).
From what I read, concierge at other deluxe hotels at WDW offer food/drink all day long, and also includes a separate check in staff as well as a separate concierge desk for reservation, questions, etc. The Swan/Dolphin does not offer this - though they have a concierge desk in the lobby that anyone can use. I don't know the price upcharge for concierge, but I'm sure it's more than $50 per night.
Hope that helps.
