At the Flamingo Las Vegas, pool access is free for registered hotel guests of the Flamingo, though you must present your room key and a matching ID. However, if you are not a guest of the hotel, you generally must pay for entry. In 2026, non-guest access is usually restricted to the "GO Pool Dayclub" (the 21+ adult pool) and typically requires the rental of a daybed or cabana, which can start at $100 to $200 depending on the day of the week and the season. Occasionally, the Flamingo offers "general admission" tickets for non-guests for around $20–$40, but this is subject to capacity and often limited to weekdays. The family-friendly "Beach Club Pool" is almost exclusively reserved for hotel guests and their families. If you are staying at another Caesars Entertainment property (like The LINQ or Caesars Palace), you may occasionally get discounted or free access, but you should always check the "Caesars Rewards" app for the most current policy during your visit.
