Check-in times at hotels in Portugal typically start around 2:00 PM to 4:00 PM, while check-out is usually between 11:00 AM and 12:00 PM. However, these times can vary depending on the hotel, so it's a good idea to confirm with the specific hotel where you're staying. If you need an early check-in or late check-out, it’s best to request this in advance, although additional fees may apply.
