The answer first
Paradise's Jeju branch page lists the first floor of Maison Glad Jeju at 80 Noyeon-ro, Jeju City. Use the branch name and address together when checking Paradise Casino Jeju or Jeju Grand results, instead of opening a Seoul, Incheon or Busan page for the same brand.

Older material may still use Jeju Grand. That helps identify historical references but does not confirm that photographed interiors, services or prices remain unchanged. Read the city, branch, address and source date first. A shared building does not make hotel and casino entitlements interchangeable.
The operator's visitor guide separately states age, identity and photography restrictions. Read its Jeju section rather than applying another branch's document table. This article identifies names, public restrictions and sources; it does not arrange casino memberships, reservations or customer transfers.
