My dd asked about the Neverland Club so during the day we went in and played there. It was just us, no other kids were there, and so she begged to come back at night when other kids would be there to play with. She's an only child and I think she gets bored with just us on vacation, lol. She has a hard time connecting with other kids. We also never leave her anywhere without us, even at home. She's 7yo, but she has a learning disability that makes her behavior a bit unpredictable and she has a hard time with complex language making herself understood (like if there was a problem with something). We plan to leave her there next visit but only for a short period of time while we remain nearby at the resort. A trial of sorts.
The club itself was like any daycare type setting inside, and I am sure all of the clubs are similar but with different themes. Toys, tv, food, video games, arts and crafts. You might try a visit to the club during the day to check it out for yourself.
