Helium balloons here usually last 8–12 hours if treated properly, and vendors often add a special gel to extend float time for bigger events. I’ve ordered 200+
helium balloons in Dubai for a birthday, and the supplier managed it fine—they brought them in large bags and filled the room ceiling-to-floor. The trick is to schedule delivery 2–3 hours before the event to ensure they look fresh. They also offer options like ribbons and confetti balloons to mix it up. Most companies are flexible, but confirm quantity limits in advance, especially for peak weekends. If you need them to stay overnight, ask for “hi-float” treatment—it makes a big difference in how long they last.
