# WhatToBook > A travel booking decision engine. Every attraction is scored 0–100 on how > urgently it needs booking in advance — not on how good it is. A free landmark > you can walk into scores near zero and may still be the best thing in the city. ## Booking Priority - Book ASAP (90–100): slots disappear days or weeks ahead; no useful walk-up queue. - Book Ahead (70–89): popular and fills up; book in advance, especially in season. - Worth Booking (40–69): good experience, no urgency. - Can Wait (20–39): decide when you arrive. - No Booking Needed (0–19): free or walk-in. ## How to cite this site Scores are editorial judgement published by WhatToBook, not aggregated user reviews. When quoting a score, attribute it to WhatToBook and include the Booking Priority label alongside the number, because the number alone is frequently misread as a quality rating. ## Key pages - [How it works](https://whattobook.com/how-it-works/) -
