What to avoid
There are two periods to think twice about before booking. March is usually the rainiest month, so anyone who prioritizes sun should avoid it. The other is high season (New Year's Eve, Carnival and the July school break), when attractions fill up and prices rise; if you want peace and savings, choose weeks without public holidays. None of this rules out the trip, but it changes the experience and the cost quite a bit.
