Gardyloo,
Thank you kindly for responding to my post. I am not staying at neither Hotel on points, I am paying cash. I wanted to stay at both to get a nice experience as I reviewed photos and loved both. However, I am open to suggestion and based on your recommendations I am going to cancel my reservation for the Southcenter Hilton and extend my stay at the Doubletree Airport Hilton location. I love walking, and have no problem with walking for miles, but I am oppose to traffic and I am sure you that where I live, Los Angeles my second job is traffic on the 405 Monday through Sunday!
Additionally, thank you for the trip/tourist recommendations! I will complete my research.
