Labor Day Camping Trip

I was planning a camping trip for Labor Day and was wondering if anyone had any details about the Patchen's Point and Gilman Island Campsites. Also does launching at Ompompanoosuc Launch point floating to Patchen's Point day one, setting up camp there then floating to Gilman Island the next day and setting up camp there before floating out to Kilowatt Park where we'd pull out on day 3 sound like a feasible plan? Thanks
