Ours did - it was very similar to the "kitchen" in the studios, though. Our Ocean view Inn Room had two queens and a sleep sofa, but I'm sure not all Inn rooms are set up exactly the same.
If this were my family, I'd probably just bring an aero bed (or something comparable) for one of the teens - there should be more than enough floor space in the 1 bedroom unit to accomodate it.
Best wishes -
