I chose to upgrade to executive floor to get club-level / breakfast and other benefits, like internet access, though not sure it was worth it (do the a la carte math first).

I ate dinner at the buffet in the lobby restaurant, and it was very nice, and a good value for the Rupiah.

The concierge lounge is well worth the price.
