Hotel stars appear to be a quality measure. They are generally a facilities checklist, and the schemes vary enough that comparing across countries means little.
What is actually assessed
Most official schemes award stars against defined criteria covering physical facilities and services.
Room size, bathroom facilities, reception hours, room service availability, restaurant provision, lift availability, and similar.
Which means a hotel can meet the criteria for a high rating while being poorly maintained, badly run and unpleasant to stay in.
Some schemes include quality assessment alongside facilities, and the weighting varies.
Why schemes differ
There is no international standard, and rating is administered variously by government bodies, tourism boards, hotel associations and commercial operators.
Some are compulsory, some voluntary, some self-assessed.
Which means a four-star hotel in one country may offer considerably more or less than a four-star hotel in another, and the difference is systematic rather than random.
Several European countries participate in a harmonised scheme, which improves comparability within it and not beyond it.
The self-rating problem
In markets with no compulsory scheme, hotels may describe themselves however they choose.
Which means an unverified star claim on a booking site may reflect nothing but the operator's opinion.
Booking platforms apply their own classifications, sometimes derived from official ratings, sometimes from their own criteria, and rarely explained.
Review scores
Now more influential than stars for most travellers, and with their own problems.
Scores cluster in a narrow high range on most platforms, which compresses the useful information.
Review volume matters more than the score, since a small number of reviews produces an unstable average.
Recency matters enormously, since management, ownership and condition change and old reviews describe a different hotel.
Fake and incentivised reviews
A documented problem across platforms.
Platforms that only accept reviews from verified stays have structurally less of a problem than those accepting any submission.
Regulators in several jurisdictions have acted against fake review brokering, and enforcement is difficult given the volume and the international nature of the trade.
Reading the middling reviews rather than the extremes generally produces the most useful information, since they tend to be more specific and less emotional.
What to actually check
Recent reviews specifically, filtered to the most recent months.
Photographs from guests rather than from the hotel, which are available on most platforms and are considerably more informative.
Location on a map rather than in the description, since walking distance claims are frequently generous.
And the specific things that matter to you — noise, air conditioning, breakfast, lift access — searched within the reviews rather than inferred from a score.
The pricing side
Hotel pricing uses revenue management similar to airlines, with rates varying by expected demand.
Which means the same room varies substantially by date, and by how far ahead it is booked.
Direct booking frequently carries benefits — flexible cancellation, room preferences, loyalty credit — that offset a small price difference, since the hotel avoids platform commission.
Platform commission rates are substantial enough that many hotels will match or better a platform rate if asked directly, which costs one phone call to find out.
Cancellation terms
Where the actual price difference frequently sits.
Non-refundable rates are cheaper and carry real risk, and travel insurance may not cover a change of plans.
Flexible rates cost more and are effectively purchasing an option, which is worth it when plans are genuinely uncertain.
Free cancellation deadlines are frequently earlier than travellers assume and are stated in the confirmation.
Resort and destination fees
Mandatory charges added at the property, not included in the advertised rate.
Which makes advertised prices non-comparable and has attracted regulatory attention in several jurisdictions.
Rules requiring all-in pricing in advertised rates have been introduced or proposed in response.
Overbooking
Hotels overbook as airlines do, and the remedy is generally relocation to a comparable property.
Entitlements vary by jurisdiction and by booking channel, and arriving late is the main risk factor.
Confirming a late arrival directly with the property is a two-minute call that removes most of the exposure.
Accessibility
Star criteria include accessibility features in some schemes and not others, and the information provided is frequently unreliable.
Which means anyone with specific access requirements should confirm details directly with the property rather than relying on a listing.
Specific questions — step-free route, door widths, bathroom layout, bed height — produce more reliable answers than asking whether a room is accessible.
Loyalty programmes
Hotel programmes generally offer more usable benefits than airline ones, including room upgrades, late checkout and free breakfast.
Status is frequently achievable through credit card partnerships without staying, which has diluted the value of earned status.
Points valuations vary enormously by redemption, and the best value generally comes from expensive properties rather than cheap ones.
Room allocation
Rooms of the same category vary considerably, and allocation is generally made at check-in rather than at booking.
Requests noted at booking are not guarantees, and asking politely at check-in works more often than most people try.
