It depends on the number of pax I think. I’ll just give you a hint though based on my training last time. For 15-20 pax we paid 8,000 for the convention center consumable of am/pm snacks Php 130, lunch 250, venue, sound, microphone, and screen. There’s an energy charge of Php 800 per day.
It’s really okay to hold meetings and seminars there. The staff are attentive and there is plenty of affordable rooms. Hope this helps. Good luck!
