Ugly Swimwear Party at The Pool After Dark, Harrah's Resort, Atlantic CityLooking for the top things to do in Atlantic City this holiday season? Ditch the traditional ugly sweater and dive into the wildest winter pool party on the Jersey Shore. On Saturday, December 12, 2026, The Pool After Dark turns up the heat for the Ugly Swimwear Party. We’re flipping the classic holiday theme completely on its head: trade scratchy knitwear for your most chaotic neon trunks, clashing retro one-pieces, and hilariously tacky swimwear under our 82-degree, climate-controlled glass dome. Providing the soundtrack for the night is DJ SPIDER, delivering a high-octane open-format set and heavy club anthems directly to the dance floor. If you're hunting for unforgettable things to do in AC to kick off the winter festivities, look no further than the premier name in Atlantic City nightlife.
