My wife and I were at the Moors twice on different weekends last month. We were just cruising around the lake in our new toy and stopped in to eat at the restaurant. I wasn't thinking about it as a Gathering site or I would have paid more attention to the details that we are looking for. I will say it appeared well kept and clean and the docks were very nice. I remember seeing a playground and miniature golf course both of which were in very nice condition and a swimming pool although we didn't walk up and look at it close. For what its worth the marina store was much nicer than Hales Bar and the restaurant is one of the better ones on the lake. I did not look at the pavilion but their web site has this photo -

Also, in mid to late September things on Kentucky lake are in the slow down mode. Not a whole lot going on so space should be available. The Moors' dock space might be a little more limited but I think it could be worked out. There is a concrete ramp right at the marina and if I remember correctly much more parking space. This was one of my main concerns with Hales Bar. I felt the builders that had trailered unfinished boats to Hales Bar were more of less orphans - lost in the confusion of the parking lot.
The Moors have a nice web site with live web cams and a lot on info -

As to Hales Bar Marina, since we stayed on the boat we didn't have the issues it seems some had with the cabins. I will say we moved our boat twice to get upwind of the honey dipper barge as the smell was very strong when it was pumping out the cabins AND it was always pumping out the cabins as it was an all day process. So it was always right there on the line with all of us.
For me the PLUS side of Hales Bar is the scenery. In my opinion,the river from there to Chattanooga is the best the Midwest has to offer. For that reason alone I would be willing to return - but again, we didn't have to suffer through the other problems. I do know if we had stayed in the cabins and they smelled like sewer I would never get my wife to back - guaranteed!
Besides the Moors I can think of one other marina on KY Lake that "might" work. Prizer Point has cabins, docks, camping and a ramp. It is a very nice facility and probably has the best camping area on the lake. It is also in a protected harbor but there is a non no wake right beside it and fairly visible. Again, was not looking at it with the Gathering in mind so closer scrutiny would be needed. Prizer Point web Site -
http://www.prizerpoint.com/We are about 170 miles from both the Moors and Prizer Point. If Dave can't make it there I would be willing to make a run down and take a better look and report back.
