EE I love your reviews and I am very glad you enjoyed the hotel. I am very impressed by your upgrade, as I received nothing when I stayed in January (I was Ambassador then), although they were apparently sold out due to the tennis, and I was on a five night stay. Were you just staying a single night?
Regarding the breakfast, I actually think the benefit is a bit stingy for Australia, as I stayed at a couple of hotels in Sydney where they just offered the full breakfast without a credit - this was Pier One and the Sheraton. I am not a big fan of the American style credit system, especially as one day they tried to charge me extra for having an omelette with the 49 AUD breakfast package - on other days, they did not.
I found the service a bit inconsistent, although well intentioned, as I had some issues with the air con that I received very mixed messages about and took basically an entire 24 hours to rectify. Eventually, I did end up with a manager apologising, moving to another basic room across the hall, and having functioning air con with an extra dyson fan, and a few points - it just felt like there was a lack of cohesion and pace to the response.
On the whole, the staff were fairly good though. I also liked the location and felt that the hotel was very well built, with an interesting array of restaurants and facilities. I would stay again.
