Booked on Dec 4 for 1 night (Feb 2015) at Courtyard Miami Beach for $40 on booking.com. Just got email that they canceled it "in accordance with our terms and conditions for obvious incorrectly loaded rates."

Looking at their T&C, there is a clause that says "Obvious errors and mistakes (including misprints) are not binding." Good for them.

Now, I was on the fence anyway as to whether I could make it, so it's not the biggest loss. But I am wondering, for future reference, if I could have done something differently.

It was refundable and not prepaid, though I did provide CC info. Is it advisable to prepay whenever possible?

Any chance of getting this kind of decision reversed?
