Quick tips

• For the most consistent “hospitality” experience choose small boutique/heritage hotels (very personalised staff attention) or established five‑star chains (robust service training and resources).
• Always check very recent guest reviews (Tripadvisor/Booking/Google) for service trends before you book—service quality can change seasonally or after management changes.
