When to SaveSan Antonio is an affordable city year-round; however, hotel bargains are harder to find when there are large conventions or major events.
When to BookBook hotels at least one month in advance for visits during the high season or popular events. Last-minute airfares and hotels are available for those with flexible travel plans. However, those with a set schedule should book flights at least three weeks in advance to obtain lower prices and ensure availability, especially for travel during the high season.
