Coz is one of those places you can just keep going back too, plenty of choice dive sites, the island life keeps changing. Last time there we stumbled onto a car show, never knew there were that many custom cars on the island!
The Hotel Coz is nice, love the tunnel so you don’t have to dodge traffic but last time our group rented a home, private pool, our own rinse tank and shaded drying area, lounging in PJ’s, not sure if I could go back to a hotel again!
