Most chalet operators start with a WhatsApp thread. It works fine for the first few bookings, then a busy Saturday arrives, two guests get promised the same weekend, and the thread becomes impossible to audit.
Why a booking link scales better
A single link with real-time availability means two people literally cannot book the same slot — the moment one guest confirms, that weekend disappears from the calendar for everyone else.
Weekend pricing without spreadsheets
Set a higher rate for Friday–Sunday once, and every booking after that applies it automatically — no manual price quoting over chat.
Headcount limits that actually hold
Capping guests per booking prevents the awkward conversation that happens when twenty-five people show up for a pool built for fifteen.
