We have teen DD & DD. Yes we bring an areotype bed with us each time and ditch it at the Dolphin before we retun home.
Last time it was a blow up type areobed with a built in sleeping bag.
Our DD almost outgrew it - but it worked for the week.
We just got a Coleman full twin sized areobed for our next trip to WDW in 2010. We plan to use the Coleman areobed during other vacations before WDW to get our money's worth. The Coleman bed only cost us $19.
You can use the extra pillows off the beds at the Dolphin. Each Dolphin bed has 4 pillows on it (8 pillows to a room).
We bring an extra set of twin sheets.
There should be an extra blanket in the Dolphin closet. If there is not one - call housekeeping and ask for one.
There is plenty of room to set up an areobed or cot in the room between the bed and the window/sliding doors.
IF you have a teen DS & DD - you may be able to get a free cot.
They offered us one to use for free the last time we were at the Dolphin, but our DD wanted the aero bed. Go figure
