The biggest regret of my current trip to San Diego has been choosing this hotel. I arrived at 11am, was told check in was at 4pm, no problem. I come back at 4pm, room isnt ready and no ETA on when it will be ready. Come back at 5pm, no room, no ETA and no act of good faith, additional points, food coupons, nothing. Finally room is ready at 5:45pm. I request late checkout to compensate for the late checkin and am denied. The AC unit does not work and the thermostat is ripped out of the wall. I tell the front desk and she "says she will send up maintenance". Maintenance doesn't come. So currently as a Marriott gold member I am sitting in a hot stuffy room that was given to me almost 2 hours late. An absolute disgrace. 

Great location, beautiful hotel, amazing views! We stayed in the Lanai building and it was very quiet. Lots of plane noise everywhere, but that's all of San Diego. The restaurants are pricey (especially breakfast). The walks along the harbor were great - 15 minutes to each end of the peninsula. Staff and concierge were very helpful. Here for a work conference and accommodations were great.
