I don't think there are restrictions. We saw the new blow-up snowmen on several sites. On the corner of our loop someone had gone all out--colored lights on all the bushes, icicle lights on the eaves of the cabin, two dimensional wreathes and other decorations on the cabin. But what really impressed me was the lightup tree and garland on their golf-cart! All we brougth were one strand of icicle lights, some colored netting (ended up on the deck) two strand of white lights to outline windows, and two rope lights to wind about the deck. We also brought a Mickey, and Tigger post for the sides of the driveway. My DH was disappointed that ours was so average!
