@TripleB909 - you asked about the island. I don’t know if that was regarding character experiences on the island or the island experience in general.
I love this professional shot of
Castaway Cay
I’ll throw you some thoughts on a Disney island or beach visit.
Two “Cays”. The original, Castaway Cay (as Gorda Cay) is an island, the entirety of which is occupied by Disney. But not entirely filled up with buildings. The theme is an abandoned island with a runway (that is actually there and used for trams).
It is low-key, rather simple, any structure sort of blends in with the environment. Imagine you built with wooden cargo boxes - but all done by Disney designers. Nothing outlandish nor glitzy. No bright colors.
The stars of the show are two separate beach areas. One is the “Family Beach,” located nearer the ship, reachable by a 10-minute walk or a short tram ride. There are a few shops, a bar, some kids play areas (hidden somewhere), a water slide feature, and food area with large pavilions for lunch. There are plenty of loungers and umbrellas, a few hammocks, and well-tended soft sand. The ocean is contained by a rock wall, forming a swimming and snorkel area. There are a lot of lifeguards.
Watercraft activities (additional cost) initiate from the area between the ship and the family beach.
An additional tram (or longer walk) will get you to the adults-only, 18+ area of the island, Serenity Bay. Here the water is more shallow, wide open to the sea. As it is the Bahamas, the depth is shallow. The water is generally extremely calm, clear, nearly colorless, and does not have a sharp drop-off. There is a small lunch area with tables/umbrellas under some trees. And birds that will steal unattended food. These same birds will tear open a bag of chips if left where they can see it. There is a bar in this area, too. Not noisy. Just there.
You can access the island and return to the ship as often as you wish in your day visit. The ship docks not too far from the tram stop. And only one ship per day.
Towels, lunch with sodas and soft serve, and loungers, umbrellas are all part of your cruise fare. Snorkeling vest is required and complimentary. Kids areas.
Extra charges: alcohol, bikes, floats, snorkel gear, watercraft, parasailing, Stingray interaction.

Serenity Bay:
Bottom line: no Conga lines, limbo, parties at the bars. Very simple, low-key. No pool. No big water park.
Yes: clean, normal bathrooms. No shower house. Go back to your cabin on the ship for that.
