None of the standard view studios at Jambo are concierge. The only DVC concierge rooms are those 5 2BR lock-offs in the club level booking category, which are usually impossible to get unless you are an AKV owner booking 11 months out. Standard view rooms are pool view rooms at Jambo or some previous savanna view rooms that were converted to standard five years ago.
Jambo House has four booking categories: Value (smaller rooms), Standard View (pool area and some partial savanna views), Savanna View (face a savanna), and Club Level (6th floor with concierge lounge access). As drusba stated, there are only five 2BR lockoffs in the Club Level booking category. If all of them were locked off, there would be a maximum of 5 Club Level studios. Anyone who books a 2BR takes one of those studios out of inventory. The small number of rooms makes the Club Level studio extremely hard to book, even at 11 months out.
