Plan to spend 1.5–2 hours if you're visiting for a dolphin and seal show only. This gives you enough time to arrive early, find your seat, enjoy the 50-minute performance, and take photos afterward.
If you've booked a swim with dolphins experience, allow 2–3 hours. You'll need to arrive 15–20 minutes before your scheduled swim for check-in and a safety briefing, in addition to attending the show if your ticket includes both experiences.
Since shows and swim sessions run at fixed times, it's best to choose your preferred slot in advance and arrive 30–45 minutes early for a smoother visit.
