What should I consider when choosing a birthday venue?

Consider capacity, location, and atmosphere when selecting a venue for your 21st birthday party. Think about whether you want a lively party or something more private. For a comprehensive guide on choosing the right venue, check out our How to Choose a Venue guide, which covers everything from budget to amenities.

What does the venue booking price include?

Venue booking prices normally include the use of the space for your event, basic furniture (like tables and chairs), and sometimes access to AV equipment. Additional services, such as catering or decoration, may incur extra costs, so it's essential to clarify what's included in the price with the venue manager when booking your venue.
