Checking in is easy. You will need a government-issued photo ID (like a driver's license or passport depending on the hotel's location) and your hotel confirmation number - which is on your itinerary.
The reservation holder must present a valid photo ID and credit card at check-in. The credit card is not only used to guarantee the reservation, it is required for any additional hotel specific service fees or incidental charges or fees that may be charged by the hotel at checkout. These charges may be mandatory (e.g., resort fees) or optional (parking, phone calls or minibar charges) and are not included in your per night price.
If you do not have a credit card some properties may allow you to leave a cash deposit for incidentals. If you plan to leave a cash deposit, please call your confirmed hotel to determine if this is possible and what the amount required is.
