I see there's a sofa bed in the King room. Is that sofa bed be pulled out as a bed?
I'm not sure since i didn't have one in my room.
I don't know. We had a room with two queen beds. If you call the hotel directly I'm sure the could answer your question. They are very helpful and friendly.
I was in a queen/queen on first floor.
Not in the standard king room. You must upgrade to a Premium King Suite or Executive Room to get a sofa bed.
