Right now, I have reservations made for the Huntington Beach Hyatt and La Quinta Waldorf Astoria. I was somewhat influenced by the fact that flight times make a trip in/out of SNA somewhat easier...although I haven't totally ruled out that Park Hyatt yet.
I'm in a temporary dip to HH Gold status, so this is also a decent time for me to sample the W=A where Diamond status, or lack thereof, doesn't matter much. By April 2016 I'll be back at Diamond, thus making a future trip down to Torrey Pines (a regular Hilton) a better idea.
