10+ for kids on our cruise this past week. We pack a backpack with our swimsuits and stuff for the day. Leave it in the bin- never had a problem with that. And plenty of chairs/loungers after the race. We change in the restrooms, use an outdoor shower to cool off/clean up a bit. We like to maximize our time off the boat on the island, so it works for us. Couple times we have had a cabana, that works out even better.
