A Four Seasons stay source attached to Prince William and Duchess Kate at Four Seasons Chicago identifies a different property. The cited HELLO! article says the couple stayed at Four Seasons Hotel Boston in the Back Bay during their November 30–December 2, 2022 Earthshot Prize visit. It does not mention Chicago.
Celebrity Hotels therefore classifies the specific Four Seasons Chicago stay attribution supported by this source as disproven. The supported relationship is instead a stay at Four Seasons Hotel Boston at 200 Boylston Street, not Four Seasons Hotel Chicago at 120 East Delaware Place.
The source mapping error
The stored source is a December 5, 2022 HELLO! travel article titled around William and Kate's hotel in Boston. Its heading says the royal couple stayed at the Four Seasons in Back Bay. The body identifies Four Seasons Hotel Boston and describes it as their base during the three-day Boston visit.
The page contains no Chicago hotel reference. Applying it to Four Seasons Chicago transfers a valid Boston accommodation statement to a sister property in another city. A shared brand name cannot establish that the same guest used every hotel operated under that brand.
The same source is attached separately to William and Kate in the Chicago hotel record, so this correction covers both exact celebrity-property combinations. It does not change the underlying Boston relationship described by the source.
Independent contemporary confirmation
Parade published its Boston itinerary on December 1, 2022 while the visit was underway. It says William and Kate checked into the Four Seasons after arriving at Boston Logan International Airport and describes crowds outside the hotel before their Boston City Hall appearance.
Parade places the hotel in a Boston-only itinerary covering the couple's November 30 arrival, Earthshot engagements and December 2 departure. Its account is independent of HELLO!'s later hotel feature and supports the same city and accommodation relationship.
These reports establish a stay in Boston. Neither publisher identifies Four Seasons Chicago, travel to Chicago or hotel activity at the Illinois property.
The government accommodation record
The United Kingdom's Contracts Finder preserves a Foreign, Commonwealth and Development Office award titled “Royal Visit Accommodation – BHC Boston.” Published on November 17, 2022, it awards hotel accommodation services to Four Seasons Hotel at 200 Boylston Street, Boston.
The contract window runs from November 28 to December 15, covering the November 30–December 2 royal visit. The notice does not publish the travelers' room assignments and should not be treated as a private reservation record. It does, however, independently identify the Boston Four Seasons property selected for royal-visit accommodation support.
The government notice aligns with the two media accounts and supplies an exact street address. It contains no Chicago supplier address.
Boston and Chicago are separate hotels
Four Seasons' official Boston page gives the address as 200 Boylston Street, Boston, Massachusetts 02116 and describes the hotel as near the Back Bay neighborhood and Boston Public Garden. This matches the government award and HELLO!'s geographic description.
Four Seasons' official Chicago contact page gives 120 East Delaware Place, Chicago, Illinois 60611-1443. The existing Celebrity Hotels record and Booking.com target resolve to that Chicago property near the Magnificent Mile.
The properties have different street addresses, cities and hotel pages. This is not a former-name change, relocation or alternate entrance. It is a sister-property identity error caused by treating the Four Seasons brand as a single hotel.
What the correction establishes
The evidence establishes that the stored HELLO! source cannot verify a Prince William or Duchess Kate stay at Four Seasons Chicago. It directly describes their stay at Four Seasons Hotel Boston during the 2022 Earthshot visit.
Parade independently confirms that William and Kate checked into the Four Seasons in Boston, and the UK government accommodation award identifies the Boston supplier at 200 Boylston Street for the same visit period.
The supported relationship remains stay, but it belongs to a different hotel entity: Boston rather than Chicago.
What this does not establish
This correction does not prove that William or Kate could never have stayed at, visited, dined at or attended an event at Four Seasons Chicago on a different trip. No universal negative is being published.
The reviewed Chicago record also carries celebrity sources referring to other Four Seasons properties in Bali, Paris and Los Angeles. Those are separate source-to-property questions and are not used as evidence for William or Kate in this article.
Four Seasons Hotel Boston is not currently an indexed Celebrity Hotels hotel entity. This workflow therefore does not add it, remap the Chicago booking listing or modify any core hotel, city or celebrity record. The correction remains an evidence article connected to the existing Chicago claim being assessed.
No hotel, press or royal-visit photograph has been copied. Images remain on the original publisher pages under the control of their owners and licensors.
Why this receives grade B
Evidence grade B requires two independent reputable publishers and a direct basis. HELLO! names Four Seasons Hotel Boston and the Back Bay stay, while Parade independently records the couple checking into the Four Seasons during its contemporaneous Boston itinerary.
The government contract and official Four Seasons address pages resolve the exact property identity. Together they show that the source belongs to 200 Boylston Street in Boston, not 120 East Delaware Place in Chicago.
Evidence verdict
Disproven: The cited 2022 source does not verify a Prince William or Duchess Kate stay at Four Seasons Chicago.
Supported relationship: Both stayed at Four Seasons Hotel Boston during the November 30–December 2, 2022 Boston visit.
Relationship type: Stay.
Correction basis: Mistaken property identity between two Four Seasons sister hotels.
Not established: Whether either person had a separate relationship with Four Seasons Chicago during another trip.
This is a narrow exact-property correction based on direct source wording and matching official addresses, not on a failure to find Chicago evidence.
