Prettiest pool for a Marriott - awesome location.
I took off one point because I am a plat member, but I though the stuffs they served at the concierge lounge in the evening sucks. They had a steak burger and a low quality cesaer salad. It paled in comparison to the stuffs served at JW Marriott LA where I was the night before. 
$38 valet parking
$26 self parking
$15 internet (free for gold/plat members)
Having said that I think their architecture is beautiful two buildings, north and south tower. The swimming pools area feel like a paradise (tropical). Its right in the harbor so the view are amazing and wonderful to walk around during the evening. Its the perfect location to be in downtown San Diego if you want to see the convention center, Seaport Village, etc. Beats the Hilton (on the opposite side of the convention center) by an arm and leg based on its location and structure. 
My favorite Marriott so far in the San Diego Area. I got yet to try the rest of them in SD (have reservations for 8 hotels coming up).
