Mullet often has some surf to enjoy, excellent beach. 12 Metre Regatta https://www.12metre.com/ is a great activity that would be fun for the kids and parents. Watching the jets come it is always a fan favorite, and the zip lines while I have not done them look entertaining. Snorkeling, several decent places.

Personally, more beach, less planned activities.

I pimp DK Gems, The Palms, Lal's, La Chingona, Dany's at Cupecoy and Friars Bay Beach Club !
