Lovely course completely spoiled by extremely slow play and no marshalling.

We have played the course 3 times over 3 years. It generally played ok but tee information was faded and needs some TLC. The course should not have accepted our booking as we were playing behind a competition. It took 1 hour 40 mins to complete the last 6 holes. It totally spoiled our round especially when the Marshall said the course would close at 5.45 pm. And that we might not get to finish our round. This is totally unacceptable when you have paid full price for a round!
