Ok, I need to understand the situation better - who is actually going to "pay for the party" in this case - booking.com or HI Baruna? I would certainly prefer the latter, as I hope that in this case my PC Plat can slightly increase my chances. But overall, my point is that for cases like that our chances are directly related to the number of complaints and possible negative publicity. Remember when CP near Venice was available for 1 euro (again, much clear cut case of "mistake rate")? It was honored, and I believe partly due to the fact that it a)lasted longer b) got some media attention.
Most of my bookings are prepaid, so I am really worried about the phrase from their email
that they will simply "adjust it" to 171 USD (again not stating even whether it includes any taxes, breakfast, etc) if I would not respond in less then 10 days.
