At Playground World, children slide, soar, and bounce through a safe and spacious party room packed with playground equipment. For two hours, up to 14 adventurous tykes can frolic unbridled aboard Woodplay Play Systems, wooden forts, climbing walls, monkey bars, and swing sets. Netted trampolines offer safe springing, and a series of Goalsetter basketball hoops unleash each child's inner Kareem Abdul McFly. Parents can stash their own refreshments in the party room's refrigerator, ensuring that ice-cream cakes won't turn into milkshakes. Playground World requires one adult for every four children attending the birthday party to help ensure safe play and to officiate arguments over who gets the corner slices of cake. Groupon customers should adhere to the party guidelines.
