When do Curaçao businesses, museums, and attractions generally open?

Regular business hours are weekdays between 8 AM and 5-6 PM but most banks close at 3:30 PM. Some stores, especially in areas with fewer tourists, may close between 12 PM and 2 PM for lunch. Stores in downtown Willemstad generally open at around 9 AM and close at 6 PM, but may stay open a little longer. Banks and offices are closed during the weekends but stores will be open on Saturdays and closed on Sundays. Most supermarkets are open on Sunday morning and only some will be open on Sunday afternoons as well. 

Museums and attractions generally open a little later than normal business hours and close a little earlier. They are usually open on Saturdays but may be closed on Sundays and/or Mondays. It's generally best to visit their website or Facebook page to check on their exact hours.
