My first thought was that it looked like a round loveseat, but the room description says that there is a pull-down bed in the Master bedroom, so that must be where the pull-down is, much like it is on the Magic & Wonder...although it looks like a tight squeeze.
And all I can say about all those chairs, is to keep in mind that it is just a rendering, we haven't seen yet exactly how many chairs are really at the dining table....but yes, I do imagine that if there are that many, it is with the idea of entertaining in mind.
I know that several of the larger suites at the Grand Californian Hotel at
Disneyland really don't SLEEP that many people, but they have large dining/conference tables.
Not what I would have designed, but no one asked me.
