There is no late checkout. However, we have often packed our belongings and stored them (either in the car or have them placed in guest storage). We keep one bag for toiletries and travel clothes. We keep that in the lockers in the fitness center. We spend part of the day at the pool, and when we are ready to leave, we shower and change. It works out very well.
We usually take the autotrain and do not need to leave until 1:30pm. We take advantage of that last wonderful morning. Sandie
