Breakfast is typically buffet; it's a fair to average buffet. Concierge lounge hasn't been open for a LONG time..... Rooms are clean/fairly modern.
Yes, there is an airport shuttle...I believe you have to call/it's not scheduled.
Restaurant-wise, there's a very good Japanese sushi/steakhouse across the street.
Transport-wise, parking is free....and there's a rail stop (to downtown or toward Tasman) beside the hotel.
