The answer first
Paradise restricts photography inside its casino and distinguishes designated areas; LES A lists camera and photography restrictions too. Check the specific operator's rules. An existing social-media image is not evidence of permission to create a similar photograph.

Hotel lobbies, casino entrances and internal areas can have different conditions. Permission in one space does not cover the building, and a past official image is not present-day approval. Check the area, purpose and current rule first; avoid unwilling people and personal identification.
Before publication, establish the place and capture date and protect companions' identity and itinerary details. Do not call an old entrance a current VIP room or illustrate Jeju with an overseas venue. Where permission is unclear, use text and a link to original official material.
