Some others to look at:
Lions Dive & Beach Resort voor een heerlijke vakantie! - AI if you add the meal plan.
Sunscape Curaçao Resort, Spa & Casino - used to be a Breezes kids resort. IDK much about it.
Curacao might be good as a family destination because there's other things to do there - the Sea Aquarium (walking distance from Lions Dive), the Ostrich Farm, shopping downtown.
For your jr. diver, many sites have a shallower component, the reef starts to drop between 30-40'. One of the signature dives - Tugboat - is 17' deep. And fully penetrable by anyone. Just about every beach also has shade, an on-site dive operator and refreshments of some type. Many are locals beaches also so there's always people nearby. At Varsenbaai there's turtles in 8' of water south of the dive dock. And squid under it often. At Nos Kas - the old Habitat resort site - I burned up my remaining air "diving" near the dock in some rocks and along the waterfront chasing flounder.
Van der Valk Plaza Beach Resort Bonaire - Bonaire is really a dive destination - not a lot else to do there. Plaza is the only full AI but about 6 of the other resorts bundle room/diving/truck/breakfast so they're a possible option. Not a lot of good beaches on Bonaire and not much else to do except dive, maybe see the Donkey farm once. Downtown is pretty small but they do have some good restaurants if you get tired of the Plaza choices. If you plan to shore dive there - most do - the entries are typically very rough over ironshore/coral rubble both at the water's edge and out in the surf line. New diver, balancing a tank, maybe not the best idea. You can also "dive the resorts" - most are on known shore dives and have dive docks - obviously other amenities also. None of the dive sites on Bonaire outside of them have any sort of facilities - or shade except for some trees/bushes.
St. Croix All Inclusive Beach Resort | USVI Vacation BEach Resort | Divi Carina Bay All Inclusive Beach Resort & Casino - don't know much about this except the shore dive at the resort is not great. Frederickstad Pier is about 25-40' deep and is dove if there's no cruise ships nearby.
Bolongo Bay Beach Resort|Fun Casual-Best All Inclusive Vacation Packages St Thomas, US Virgin Islands - on the quieter East side of St. Thomas. St. Thomas Dive Club there has been mentioned as a beginner friendly operator. Bolongo Bay is older so IDK what condition it's in. Most of the dives in that area don't get much below 50' - Cow/Calf Rocks - one of the better dives - has a maximum depth of 40' We did some drift dives off the Cays (Grass, Congo, etc.) and I'm sure we never broke 50'.
Before you ask, Ocean Encounters has a shop at both Lions Dive and Sunscape, Toucan Divers is on-site at the Plaza, the Divi has a Cane Bay dive shop on site and STDC is on-site at Bolongo as mentioned above.
