Family tips and best practices
Bring life jackets or water wings for young children if you prefer extra flotation; the property has a splash pad rather than a separate kids’ pool, so small children will want supervision near shallow features. The lazy river and infinity pool are family-friendly.
Plan swim times outside peak check-in/out windows and major convention events for a quieter experience. If you're visiting during cooler months, check whether the pool deck is hosting a movie night or special event.
- Supervise children at all times — children under 16 should be with an adult in pool areas
- Ask the front desk about pool lifeguards or staff on duty during your visit
- Reserve cabanas ahead of major events or weekend stays to secure shade and seating
| Situation | Tip |
|---|---|
| Traveling with toddlers | Bring floatation aids and stay near the splash pad |
| Family photo | Use the infinity-pool edge viewpoints when not crowded |
| Spa visit with kids | Longer spa treatments include rooftop access — plan pool time around appointments |
