Enjoy the hot tub. For more intimate gatherings, or as the night wears on and the temperature drops, the hot tub is a perfect way to warm up and get to know your friends really well. You can always just put your feet in if donning a swimsuit sounds more like a punishment than a party. Having a spa near the entrance to the house is convenient for the swimmers as well as for people who choose not to partake but still want to join in on the fun as the party draws to a close.Do you dare entertain outdoors in winter?
