Travel insurance generally covers unexpected events like trip cancellations, medical emergencies, lost luggage, and travel delays. While it's not mandatory, having insurance can provide peace of mind and financial protection during your travels. Depending on your destination, length of stay, and activities planned, the level of coverage you need may vary. It's always a good idea to compare different policies and check the specific inclusions and exclusions. For detailed advice, consider speaking with a licensed insurance professional or visit a reputable insurance comparison site.
