Regulating sun lounger reservations in Mallorca hotels

There is no pan-European rule governing towel-based reservations. Hotels can set house rules to ensure safety and comfort, including visible pool signage with time limits, staff checks, and penalties such as removing towels or restricting the right to reserve loungers. Some hotels also use numbered loungers, reserved slots, wristbands, or booking apps to manage demand and make enforcement clearer. Enforcement should be proportionate and well-communicated, and local authorities may be involved if tensions escalate.
