Pam is right, book now.
The resort provides daily activities for kids & adults with the best CMs of all the resorts. The turtle nesting season is March thru June so you will approaching peak time. The resort has organized searches lead by a naturalist (night time), but this is popular and the attending group is selected by lottery. Still if you don't get selected you can venture out on your own to walk/search the beach.
They have a nice pool & Lighthouse w/spiral waterslide, a REALLY cool water play area for the real young kids, a hot Jacuzzi, miniature golf, exercise room, ping pong, bike rentals, The Green Cabin Room (bar/restaurant) has 2nd floor covered deck that has a fantastic view of the ocean and is a nice place to relax with your favorite beverage. It also has live entertainment in the evenings. Some nights they have a campfire / smore roast (bring the Cutter Advanced to fend off the No-see-ums). You can rent a small catamaran or jet-ski for ocean fun (water might be to cool yet). Across the street they have a lake, picnic tables, nature trail, tennis courts, and basketball courts. Disney built a private tunnel under the road to access this area. And of course they have the ocean and great waves for boogy boarding. Everything from the ocean to the pool to your room is no more than 2 minutes away walking. So it is real easy to break up your day
Five minutes away is Pelican Island and a wildlife education center. Also minutes away is Sebastian Inlet were the Indian River meets the ocean. There are many good fishing spots around the inlet, and there are river excursions where you can see dolphins, manatee, and tons of other types of wildlife. About an hour away is Cape Canaveral, (where the Magic and Wonder dock), the Kennedy Space Center (with museums,tours, and shows), and Merritt Island National Wildlife Refuge with walking and driving tours.
Have a great time.
