Vienna experiences its high season from April to October, with July, August, and the main festivals being the most crowded times. Bookings around Christmas-time are also heavy, as many Austrians themselves visit the capital during this festive time. Always arrive with reservations during peak seasons. During the off season, hotel rooms are generally plentiful and less expensive, and there is less demand for tables in the more popular restaurants.
