One week before the tour I guide advised us that it was most unlikely to go ahead.
We responded to his message but got no response back from him.
At 3 pm the day before the tour we were told that it was going ahead.
We turned up as advised at 9:20 am and waited until after the advertise start time of 9:30 am. When the guide had still not turned up at 9:45, we left.
In addition to all these frustrations, we wasted money paying for unnecessary car parking.
