I prefer plane spotting views, however my biggest gripe is the lack of hot food options. If the food situation got addressed and they renovated the place to look more inline with the newer Qantas domestic lounges, it would be much more pleasant.
Also more yellow lighting instead of the harsh whiter lights will make the place feel warmer.
Im usually a leisure traveller, so my needs are probably different. If I had to punch out some work it would be a great place to be due to seat capacity and fast internet.
