I was wondering as well if the North Koreans staying at the Walker Hill Hotel had some kind of symbolic meaning to it, but apparently is was all about security:
Walker Hill Hotel
North Korea again chose Seoul’s Walkerhill Hotel for its high-level delegation’s lodgings during the delegates’ three-day visit. The North Korean leader’s sister, Kim Yo-jong, and other delegates stayed there three weeks ago.
A question then arises: why does the North prefer the hotel out of numerous luxury five-star hotels in Seoul?
An irony lies in the hotel’s name. It was named after U.S. Army general Walton Harris Walker, who died in an unfortunate car accident during the 1950-53 Korean War. Walker was credited with crushing North Korean troops in many battles, paving the way for the ultimate victory of the combined forces of South Korea and the United Nations.
Experts cite security as the first and foremost reason.
Unlike other luxury hotels in central Seoul with many access routes, Walkerhill is surrounded by Mount Acha and linked with only a handful of narrow roads.
For that reason, Walkerhill was a favorite venue for secret inter-Korean meetings in the 1980s and ’90s. [Korea Times]
