How it is rated
Every number on this site is computed from Interval International's own public directory. Nothing is a review score and nothing is guessed at — where the evidence runs out, the site says so rather than inventing a value.
What was crawled
The directory is walked in full: all 31 regions, all 376 areas beneath them, and every resort listed in each area — 2,447 properties across 82 countries. For each one the site records the quality tier, description, on-site and nearby amenities, unit configurations, check-in days, nearest airport, coordinates, photos and the Travel Demand Index chart for its market.
The two things the directory does not tell you
Interval's structured amenity list stops at "Cooking Facilities (In Units)" and "Laundry Facilities". Neither answers the question that matters on a long stay: is it a real kitchen, and is the washer in the unit or in a shared room? Those details are almost always in the resort's description prose instead, so the description is mined for them and the matched wording is quoted on the resort page as evidence.
Kitchen
full- Full kitchen
mixed- Full kitchen in some units
unspecified- In-unit cooking (grade unstated)
kitchenette- Kitchenette only
none- No in-unit kitchen
Laundry
in_unit- Washer/dryer in unit
mixed- In-unit laundry in some units
shared- On-site laundry facilities
none- No laundry noted
Second source: the resort's own website
Interval leaves both questions unanswered for most of the directory, so where a resort has its own website — not a brand homepage shared by dozens of properties — that site is read too, in English, Spanish, Portuguese, Italian, French and German. 993 sites were read this way and resolved a further 462 resorts.
robots.txt is fetched and obeyed for every host, at most three pages are read per resort, and requests to one host are spaced out. A website finding never overrides Interval's own wording — it only fills a genuine unknown, and the resort page labels which source each answer came from.
unspecified means the resort has in-unit cooking but never says of
what grade. It is scored between a kitchenette and a full kitchen rather than
being treated as either — an unknown is not evidence of absence.
The dimensions
Each is scored 0–100 and each can be ranked on independently.
| Dimension | What it measures | Weight in overall |
|---|---|---|
| Quality tier | Interval's own audited designation: Elite, Premier or Select | 26% |
| Self-catering | Kitchen grade, in-unit laundry, grocery access | 16% |
| Space | Bedrooms and sleeping capacity of the largest units; lock-off flexibility | 14% |
| Amenities | Breadth of on-site provision across twelve amenity groups | 14% |
| Wellness | Spa, sauna, fitness room, hot tub, pool | 10% |
| Dining | Restaurant, bar, live entertainment, groceries | 8% |
| Beach & water | Beach access and water sports | 7% |
| Convenience | Airport proximity, Wi-Fi, step-free access | 5% |
| Family | Children's amenities, pool, capacity, self-catering | — |
| Golf · Ski · Tennis | Activity access, on site or nearby | — |
Golf, ski, tennis and family are deliberately left out of the overall score. They describe what a resort is for, not how good it is, and including them would mark down a fine beach resort for having no ski lift. Rank by them directly instead.
Two rules that shape every score
On-site beats nearby. A beach at the resort and a beach you must drive to are different products. Nearby amenities count for roughly half.
Absent evidence is not negative evidence. A thin listing is not scored as though the resort lacked the features it never mentions. Unknowns are scored neutrally, and each resort page reports its own data coverage so you can see how much was actually known.
Travel Demand Index
Interval publishes the TDI only as an image per market — a 53-row grid on a 50–150 scale where 100 is that market's average demand. The site reads those charts back into numbers off the image lattice, and joins each row to the real calendar dates of that timeshare week. Marker colour carries meaning: a value can apply to both years the chart covers or to just one, which is how holiday drift such as Easter shows up.
Week numbering follows Interval's calendar — week 1 begins on the first Friday of the year. See the full calendar.
Limits worth knowing
- Ratings describe facilities, not service, upkeep or guest satisfaction. A resort with every amenity can still be poorly run.
- Kitchen and laundry findings are read from marketing prose, so they inherit its vagueness. The quoted evidence is shown so you can check it.
- The TDI grid resolves to 5-point cells, so values are the centre of a cell rather than an exact figure.
- Interval's own data has occasional errors — a handful of southern-hemisphere resorts carry a positive latitude, for instance.
- Availability is a members-only, live question. Nothing here reflects what is actually bookable.
