I heard there's a lag between the bookings and the actual revenue. Eg, say checkin has a huge amount of bookings in the months of Oct/Nov, but also say the majority of those bookings may only convert to nights in March/April next year. The actual revenue doesn't appear until the month the customer actually stays at the hotel. So, looking at these numbers, you could potentially double/triple the amount of bookings that have already converted. Just my own prognosis. DYOR.
