If you pick the PH Aviara, bear in mind that posted rates per night are $60 less than you will actually pay, due to a $30 resort fee (probably waived on a points stay) and a mandatory, inconvenient $30 valet parking fee (probably not waived on a points stay).
Valet parking is also usually mandatory at the Andaz WeHo and also at the HR Century City which is not far away.
