When to SaveOctober through April is the least expensive time to visit, when the city sees fewer visitors. Prices rise between May and September, when tourism and demand peak. Discounts and packages are typically available in the shoulder seasons.
When to BookBook by December or January for visits during the summer high season, and at least two to four weeks in advance for stays in the winter low season. If traveling during the shoulder seasons, make arrangements two to three months in advance.
