Floating around on a raft by yourself all day isn't as much fun as floating around with a small friendly crowd. The cool new Floating Party Mat is a massive floating foam mat that can support up to 6 adults or 500+ pounds, but unfortunately only has 4 built-in cupholders. Perfect for the beach, a lake, or a giant swimming pool and even includes mooring lines if you want to keep your party from floating away. Hmm, I guess floating around by yourself wouldn't be so bad if your float was 15 feet long and 6 feet wide.
