What the trend suggests
Possible renovation2015-08 – 2016-0172% confidence
A 6-month gap (2015-08 to 2016-01) shows pre-gap rating of 5.0 and post-gap rating of 4.0 (delta -1.00). However, reviewing the immediate post-gap months (2016-02 onwards), ratings recover to 5.0 by Aug 2016 and stabilize at 4.5–5.0 thereafter. The extended closure and subsequent recovery is consistent with major renovation or repositioning, though the initial delta is negative rather than positive. This may reflect a transition period rather than pure renovation.
Issue resolved2020-Q4 – 2026-Q378% confidence
Early reviews (2020–2021) frequently cite 'rooms are dated/old', 'marked by age', and 'not 5-star standard' (e.g. 2020-Q4, 2021-Q3, 2021-Q4, 2022-Q1 snippets). By 2024 onwards, complaints about room age/dating decline sharply, and recent reviews (2025–2026) praise 'modern', 'luxurious', 'beautifully designed' interiors, particularly in the Design/Luxury buildings. Suggests targeted room renovation programme completed by late 2023–2024.
Emerging issue2019-06 – 2024-Q276% confidence
Restaurant service and food quality complaints cluster in mid-to-late 2019 and peak in 2020–2024: long waits (2–2.5 hrs between courses), overpricing relative to quality, cold/slow service, and inconsistent staff attention appear repeatedly (2021-Q3, 2022-Q1, 2022-Q4, 2023-Q4, 2024-Q2). By 2024-Q3 onwards, restaurant issues diminish in frequency, though lingering complaints persist (2024-Q3, 2025-Q2). Overall confidence that restaurant service was a sustained weakness is moderate-to-high.
Possible recovery2020-09 – 2023-1273% confidence
Following a dip to 3.5 in 2020-09 and 3.0 in 2020-10 (post-COVID operational disruption), ratings recover progressively through 2020-11 (4.5), 2021 (mostly 4.0–5.0), and stabilize at 4.5–5.0 from 2022 onwards with only minor fluctuations. Review volume also grows from sparse (1–3 reviews/month in 2020) to consistent 3–8+ reviews/month by 2022–2023, consistent with resumption of normal tourism and operational stability.
