The honest version
Anytime Booking is a well-established UK campsite and holiday-park system that’s served a lot of parks well for years. It’s full-featured, and for a complex holiday park with statics, owner sales and detailed PMS needs, it’s a sensible choice worth keeping.
Where owners move to CampSuite™ is the large middle ground: campsites and touring parks that want a modern, mobile-first booking diary and much better value, without a full holiday-park PMS wrapped around it. If most of Anytime Booking’s depth goes unused, you’re paying for weight you don’t carry.
