Everything that Kathleen Templeton explained to you is correct. There are all these things available to you.
However, here is the glitch - Disney makes them available (adult or not)
to all the children on the ship - that is correct - all adult bars, etc.
I sailed on Disney in July, 2006. I know first-hand.
I cannot imagine what it would have been like if I had sailed solo.
This was my first cruise, so I guess everyone is entitled to make a very costly mistake!
Never again, solo or otherwise!
