Cultural Tip
In Brazil, it is common to confirm the guest list at least 48 hours before the event. Changing the number of guests after that may incur extra fees, especially at restaurants and hotels. When you ask to change the count, be ready to give a clear new total and, if possible, a brief reason – this helps the host accommodate you smoothly.
