And when we were there, the buses leaving from the PPP seemed pretty frequent. We left the MK around 11:20, and only one family was waiting at our stop, to get back to our hotel. They said they had just missed the last bus, which had just left, so it would prabably be a while before another one came, but it was only a minute or two till the next bus. We rode back, just their family and ours. Of course it would be a little more crowded at midnight, when it closes, but the buses seemed to be running really frequently.
