For West Palm Beach, your best bet in April is John Prince County Park Campground, in Lake Worth...10 minute drive from just about anywhere in the WPB area. Ask for a lakefront site if available (and if you won’t be there longer than 14 days; longer term is possible but not at lakefront sites). They take reservations (by phone only, no online reservations) 90 days before your arrival date.

Alternatively, there’s the Lion Country Safari KOA out in Royal Palm Beach, but you’re 30 minutes from WPB and it’s quite pricey. But if you like the idea of hearing the Lions roar from your campsite, then by all means, have at it. 😁
Jonathan Dickinson State Park is in Hobe Sound, about 40 minutes north of downtown WPB.
Of these, I’ve only stayed at John Prince, and I recommend it highly.
No matter where you choose, if you have a dog, be aware of South Florida’s growing population of invasive, poisonous cane toads. Depending on its size, your dog would likely die from contact.
