From what I read on LL SYD is getting a refurb over a period of years. Don't know why it takes so long
QUOTE: InterContinental Sydney has been an iconic feature of the city skyline since it opened in the 1980s. With its unrivalled hospitality and some of the best views in Sydney, it’s a true favourite with travellers to Australia, including celebrities, world leaders and other high-profile guests, and will proudly continue as part of the InterContinental Hotels & Resorts family.
A significant investment into refurbishments and renewal will take place over the coming years and will see the hotel elevated to even higher levels of luxury and sophistication. It will be the first major upgrade since opening, and it is anticipated to add event spaces, including a grand ballroom, that will show off the Sydney Harbour Bridge and Opera House panoramas to anyone fortunate enough to visit.
