Reviews
what people actually sayWP Simple Booking Calendar is a well-regarded, stable calendar plugin for rental and booking use cases with consistently praised support, but the free version is widely seen as too stripped-down to be genuinely useful on its own.
What people like
- +Support team is consistently responsive, helpful, and technically capable×6
- +Plugin is stable and reliable over long-term use×3
- +Pro version supports calendar syncing (e.g. Airbnb, Booking.com) that works well×2
- +Can be extended and customized beyond its 'simple' branding, including integration with ACF and Elementor
- +Free version is sufficient for single-item rental use cases
Common complaints
- −Free version is heavily restricted — basic functions like renaming or deleting legends are locked behind the Pro upgrade, making it feel like an unusable demo×2
- −Pro licensing does not accommodate staging environments, requiring deregistration and re-registration when promoting from staging to live
