It is between 10-15 minutes. You can get there faster by car but you would be missing out on a really beautiful and relaxing trip. Plus, you get to see the Disney TreeHouses where the International Cast Members stay during their time at WDW.
Just to add to this.
The ride is approx. 15 minutes each way from POFQ and very relaxing. They run frequently every 10 to 20 minutes throughout the day up to around 11:00 to 11:30, depending on the day of the week.
Non-stop service from POFQ. You can also bump a ride up to Riverside from POFQ. If you like relaxing free boat rides, you can take one to DTD and jump on one to OKW or SS. They also run one from the east side of DTD to the west as well. Even if your not a guest at any of the resorts, the ride is free to all. They never ask for any room credentials. Very impressed on how they can steer them in the dark with minimal light.
Interesting note on the treehouses, our captain on our boat mentioned they will be torn down soon and new condos will be built to satisfy the disabilities act. They were built back in the 70s but were discontinued in the late 80s due to the disabilities act, a lot of decks and stairs. Since then they were used to house student employees on a temporary basis. Very interesting architecture to look at.
On the bed comment, it is correct that all moderates have either full/twin or King. If at least they made a queen option out of one of the beds, that would make a huge difference.
