What are the rates for the cabins?

For a grooms party, probably ideal. There are 2 bedroom ones that sleep 8 I believe it was (2 bunks and 1 queen). October is off season so it would be the cheaper rate. Just remember, keep it classy, it is a beautiful park ;) hope you enjoy. https://www.reserveamerica.com/explore/occoneechee-state-park/VA/140179/overview This should bring you to the rate and reservation site. Cabins were fully stocked with kitchen items, linens and pillows on beds etc

Some of the cabin cost about the same as some rooms. We be staying at Lake motel.

I'm sorry I don't know, we use the boat ramp their to unload and load our boat. That's 7.00 for the day. It's a real nice place if you haven't been there, definitely worth going too !

I'm just not sure because I get married in October and I know Clarksville pretty well but am unsure as to how the cabins would be for the groom's wedding party

Cabins are typically good. Last trip (this April) we had a coolerator issue in cabin 8. We were also visited frequently by sugar ants in the kitchen. I can get ants in a tent, but generally don't. Bring a cooler and you should be OK. Beautiful park.
