Best Venues for Mid- to Large-Scale Meetings in Seoul
Seoul has become one of Asia’s most reliable destinations for medium and large meetings. The city offers strong infrastructure, efficient transport, and a growing number of venues that can handle groups from a few hundred to several thousand people without compromise.
Here are four venues that consistently perform well for planners looking for practical capacity, good logistics, and a professional atmosphere.
COEX Convention & Exhibition Center
Located in Gangnam, COEX remains the default choice for most large international meetings and conferences in Seoul. The complex offers multiple exhibition halls and more than 50 meeting rooms. Its largest spaces can accommodate well over 1,000 people in theater style, and several rooms can be divided or combined depending on the program.
The biggest practical advantage is convenience. COEX is directly connected to a major subway station, two InterContinental hotels, and one of the largest shopping malls in the city. Delegates can move between sessions, hotels, and meals with minimal friction. For groups of 500–2,000 people that need both plenary and breakout rooms, COEX is still the most straightforward option.
Grand Hyatt Seoul
Situated in Itaewon with views toward Namsan, the Grand Hyatt is a strong hotel venue for meetings that require a higher level of service and a more contained environment. Its Grand Ballroom can hold up to around 2,000 people for large sessions or dinners, while smaller meeting rooms and suites are available for breakouts and private discussions.
The hotel works particularly well for groups that want everything under one roof—accommodation, meeting space, and catering—without the scale of a pure convention center. It has earned solid rankings among meeting hotels in Asia-Pacific, largely because of consistent execution and the ability to handle both formal conferences and more social evening programs.
Also in the COEX area, this hotel offers a large, column-free Grand Ballroom that can seat roughly 1,000–1,500 people depending on the setup. The space is flexible and can be divided, which makes it useful for conferences that need a main hall plus supporting rooms.
Because it sits next to COEX, planners often use it as a hybrid option: the hotel for smaller sessions, VIP dinners, or overnight stays, and the convention center for the largest plenary. The connection between the two properties reduces transportation hassle for mixed-size programs.
Conrad Seoul
For groups that prefer a more modern hotel setting in the Yeouido business district, Conrad Seoul provides a clean alternative. Its meeting rooms and ballrooms can handle several hundred people, and the hotel has experience with international financial and corporate events. The location works well when the agenda includes nearby corporate offices or when planners want a slightly quieter base than Gangnam.

How to Choose
For pure capacity and the ability to run multiple sessions at once, COEX is usually the safest starting point. If the group values hotel-level service, food quality, and the ability to keep most activities in one place, the Grand Hyatt or Grand InterContinental tend to be stronger fits. Conrad Seoul is worth considering when the meeting has a strong corporate or financial focus and Yeouido is logistically convenient.
Most of these venues are well connected by subway or short taxi rides, and Seoul’s public transport is reliable enough that large groups rarely face major movement issues. When planning, it is still worth confirming current room configurations and any technical requirements early, as popular dates fill quickly.
Seoul’s strength is not just the number of large rooms, but the combination of modern facilities, efficient infrastructure, and the ability to pair formal meetings with the city’s broader appeal. For mid- to large-scale meetings, the venues above cover the majority of practical needs without unnecessary complexity.
