G-CIVC So glad to hear you liked it!
I've been annoyingly telling everyone how much I love this property and how I believe it's hands down the best in HK...glad to see others experiencing and loving it.
I do think the views are in Harbour Corner and Grand Harbour Corner Suite are noticeably better though.
Value wise, I'd say, if anyone is considering booking a Club Grand Harbour Room then it's better to book the Kowloon Peak View Suite (which is usually nearly the same price) through a Rosewood Elite TA and upgrade at booking to a Deluxe Harbour Suite (usually about a $300++ - $450++/night value) with Club access. So you'd end up in a bit less view suite for about the same price and the suites are amazing, as you pointed out

Otherwise, I think the next value point is Harbour Corner Suite and upgrade at booking to the Grand Harbour Corner Suite which is worth about $400 - $500+/night difference.
Sorry to hear about the Club experience though. Heading back in a few weeks and will see how it's going and report back.
Nonetheless, glad it was positive overall
Cheers,
