We are going to WL in March for a week. Because one of the nights was not available at code rate, I had to book 3 reservations - 1 night code, 1 night rack, 5 nights code. However, I did keep trying to get the rack rate night at code rate. After almost 10 days of trying, I finally hit pay dirt this afternoon. Now that I was able to get the night at the code rate, guest services was kind enough to combine the reservations into one reservation. So no worrying about room switches or having to check in three times.
