Better to inquire at Edna's Beach and Campsite directly by sending them DM's for updated package and accommodation. However, you may prepare at least Php 2,000 per head unless you will buy a lot of *pasalubong, that's more than the budget. Since you're a commuter you cannot bring bulky items for camping. So be prepared for several miscellaneous fees.
Space for your tent, tables and chairs, water, electricity, and bonfire. Speaking of bonfire, they have designated space and time for it. It's located in front of shower rooms, adjacent to the grilling area. A little far from the camping site. Better to prepare food and activity for that event.
