The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Happened as dated, per the source: "The first guests have checked into Ciel Dubai Marina, the world's tallest hotel."
IHG's own press release, dated 17 November 2025, confirms the same opening two days after The National's report and the pin's stored 15 November 2025 date, a minor gap likely reflecting press-release timing versus on-the-ground reporting.[1]
The National reports Ciel Dubai Marina welcoming its first guests and opening as the world's tallest hotel, announced 15 November 2025, matching the pin's stored date exactly.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
