One of the most traveler-friendly aspects of Las Vegas is that you do not have to pay an entry fee to walk into a casino. Nearly all casinos on the Strip and Downtown are open to the public 24/7 for free. The casinos are designed to be as accessible as possible to encourage visitors to stay and play. However, while entry is free, you should be mindful of other associated costs. Most major resorts now charge for parking (both self-park and valet), and if you are staying at a hotel, you will be hit with a daily resort fee (often $40–$55 plus tax) that covers amenities like Wi-Fi and pool access. Additionally, while you can explore the gaming floors freely, you must be at least 21 years old to gamble or loiter near the slot machines and tables. Some high-end lounge areas or pool clubs within the casinos may charge a cover fee, but the main casino floor itself is always free to enter and wander through.
