Hotels often give wristbands for a variety of reasons, but it's most commonly associated with all-inclusive resorts or properties with amenities like pools, beaches, or special events. Here's why:

Identification: Wristbands help staff easily identify guests who have access to certain amenities or services. For example, at an all-inclusive resort, guests might wear different colored wristbands depending on the level of their package or access to particular activities.

Security: Wristbands can serve as a security measure, ensuring that only paying guests have access to certain areas like pools, fitness centers, or private beaches. This helps prevent unauthorized individuals from entering these spaces.

Convenience: Wearing a wristband is often more convenient than carrying around a key card or ticket for access to amenities. It's also more difficult to lose or misplace, especially in water-based environments.

Marketing and Branding: Some hotels use branded wristbands as a form of marketing or branding. Guests wearing these wristbands become walking advertisements for the hotel, especially if they venture outside the property during their stay.

Tracking: In some cases, hotels may use wristbands for tracking purposes, such as monitoring guest participation in activities or keeping track of food and beverage consumption at all-inclusive resorts.

Overall, wristbands are a practical solution for hotels to manage guest access, enhance security, and provide a seamless experience during their stay.
