Check what the condo offers: kitchen utensils and cookware, plates, silverware? Is there a pool at the condo? A park? Free stuff to do? Also, the condo office will know what's fun to do locally or any kid friendly events. Find out if you can ship stuff to the condo so you dont need to pack it. like beach towels, sand toys, extra swimsuits, sunscreen. beach hats. stuff that's bulky but needed!
