It’s best to book at least 2 to 3 months in advance, particularly if you're looking for a venue during the summer months or the busy holiday season. Bath is a popular tourist destination, and many venues can fill up quickly. If you’re planning a party during a busy time such as the Bath Christmas Market or during university graduation periods, it’s crucial to book even earlier to get your preferred space. Consider booking up to 6 months in advance for large parties.
Most venues in Bath allow you to decorate the space to match your party theme, but it’s important to check with the venue manager beforehand. Some venues provide basic decorations or allow you to bring in your own, however, there may be certain restrictions such as no confetti, candles, or sticky tape on the walls. Venues near the Bath Abbey or in the city center may have historical restrictions, so always clarify the rules about decorations when booking. Some venues also offer additional services, such as decoration packages, to make the process easier.
