Do long weekends fill Foz do Iguaçu?

Yes, with official data: over long weekends Foz hotels jump from the month's normal pace to 76-95% of rooms taken (SMTU Foz, 2021-2026). The only measured exception is Christmas, which stays at the normal pace or below, a stay-home holiday.

Is a long weekend a good time to visit Foz?

Depends what you want. Long weekends bring peak buzz, but hotels run nearly full (76-95% of rooms) and attractions carry high busy-day odds. Ordinary weekdays in the same month have far more room available, and travelers outside holidays usually find better rates and shorter queues.

How to read: the numbers are the share of rooms taken. Example: on May 1st, 81% of Foz's rooms are occupied, versus 57% across an ordinary May. Average of measured years (2021-2026, SMTU); comparison month excludes 2021.

Expectation × reality

Hoteliers underestimate their own long weekend

Before each extended holiday, SMTU asks hotels how full they expect to be, and reality almost always beats the guess. On Labor Day (May 1), for instance, they expected 73% of rooms taken and got 81%. The city fills up MORE than its own hoteliers predicted.
