Adding onto to this… my son is a competitive swimmer and trains 5-6 days a week. He’ll be newly 12 when we go. He just swam the mile at the State meet this weekend. Would he be okay without fins? We are thinking of bringing his training snorkel vs renting, but the fins take up quite a bit of space, although he does use the short ones. My 10 year daughter is also a strong swimmer, but doesn’t have the endurance he does but this is high on her list. I’m thinking she’d need fins for sure? She also has a training snorkel we could bring.
