i would call the front desk, they ask for ID and CC though.

Dear Traveler, The Las Vegas/Summerlin Courtyard Hotel does not have any guest rooms that can be accessed directly from the parking lot. The lobby entrance is not the only entrance to the building.There are hallway entrance/exits on the ground floor that can be accessed, using your room key, from various areas of the parking lot for your convenience. I hope this answers your question and we have an opportunity for you to stay with us.

Hi Rick, The Summerlin Courtyard, 1901 N Rainbow Blvd, is approximately 16 miles from McCarran airport. I am not pesonally knowldedgeable of how Citizens Area Transit (CAT) works in Las Vegas but I was able find some information on their website. Their note says "You can find their new web site at rtcsouthernnevada dot When I entered the link it said it was not available but I was able to click on topics in the heading such as "Transit" which took me to drop down boxes for more information -Airport Transit Routes, etc- Traveling to McCarran International Airport? Route 108, Route 109, and the Westcliff Airport Express all stop at the airport’s Ground Level Zero at Terminal 1. If you are traveling to Terminal 3 you can now take the Centennial Express and the Westcliff Airport Express. Please note that the Centennial Express only goes to Terminal 3. Download our Airport Park & Ride Airport Guide for information about all transit route schedules at McCarran International Airport. You can also access the airport on the Strip & Downtown Express by going to the South Strip Transfer Terminal (SSTT) and riding Route 109 straight there. To plan a trip online, use the Google Transit Trip Planner located on our home page. At the airport, purchase transit passes using the Ticket Vending Machines (TVM) located at the bus stops on Level Zero of Terminal 1 and 3. TVMs only accept Visa or MasterCard credit/debit cards. Alternately, you can purchase your pass when you board the vehicle. Please have exact change ready. The Westcliff annex is the closest to us- approx. 1.5-2 miles away. I hope this information is useful for you.
