Summer Leisure
Cosmos Hall (Banquet Hall)
The Cosmos Hall at Hamilton Hotel Seoul provides a versatile setting for guests who need a dedicated venue for events, celebrations or professional gatherings. The hotel describes the banquet hall as suitable for occasions ranging from intimate gatherings to larger celebrations.
The hall can accommodate different types of functions, including family events and corporate seminars, making it useful for both private and business occasions. Whether you are organizing a company gathering, seminar or special celebration during your stay in Seoul, the Cosmos Hall gives you the convenience of holding the event within the hotel.
For guests traveling as part of a group or attending an organized function, having an event venue within the property can also make arrangements more convenient. Combined with the hotel's accommodation and other facilities, the Cosmos Hall adds another practical option for travelers who need more than simply a guestroom.
Overall, the Cosmos Hall is worth considering for visitors looking for a flexible hotel event venue for social gatherings, celebrations and corporate functions.
Business Meeting Room
For smaller and more focused business gatherings, Hamilton Hotel Seoul also provides a dedicated Business Meeting Room. The hotel states that this compact meeting space is designed for small groups and business meetings of up to 20 people.
The room includes useful presentation and meeting equipment such as a projector, automatic screen and whiteboard, helping make it suitable for presentations, discussions and small corporate meetings.
This makes the Business Meeting Room particularly useful for business travelers who require a professional space without needing a large banquet hall. Its smaller capacity provides a more focused environment for team meetings and other small-group business activities.
Together, the Cosmos Hall and Business Meeting Room give guests two distinct options: a versatile banquet space for events and celebrations, and a compact, equipped meeting room for smaller business gatherings.
