This must be a trial, has not happened to my searches. Just did one (Australia). This is bad news indeed for those who do not want it.
@Melanie58, I know you are a fan of IB, I can't see a way around it for me. Here is my really common scenario, see if you can solve it:
I have a two night minimum on weekends. We are in a wedding area, so if I allowed single weekend nights I would be booked a single Sat every weekend of the year. Despite me saying TWO nights only guests send requests all the time, which I have to decline. BUT: If I make my calendar so you can only ask for two nights, then what happens to all the stray weekend nights which crop up through the year? Example: Guest A books Thu-Fri, checks out Sat. This leaves Sat free as a one nighter, and I will book it as such. Another week there will be a check out Fri, next check in Sat. Leaves Fri free. If I have a two night official min, how will guests be able to book those?
Also, guests book inappropriate things like young children, booking for others, etc. They try quite regularly, but at the moment I have a chance to talk to them first and I hardly ever have to decline a booking, except for the Sats mainly! With IB I would have to cancel more than three grace bookings. I would probably have to cancel 52 per year. Solution?
