There will be a table on the stage on the lawn where you can set up. Since you will start to play any time from 19:45/20:00 depending on the jazz band before you and the audience's mood, you should probably arrive to set up around 19:00, right? Maybe earlier. I will leave it up to you to contact my wedding planner Khun Ja to coordinate. Do you know her? Please contact her about all audio-related set up or speak to Dhara Dhevi directly. Do you have their contacts?
