Overall, I had a very nice weekday stay here (Sunday night to Monday), and I would recommend the property during the week. However, due to the breakfast exempt status and the closed lounge on weekends, I think there are better value properties in San Diego for weekend stays (such as the Westin Gaslamp). Still, for a sold-out property full of convention-goers (multiple appeared to be hosted at the hotel on the same day), it felt like they had their operations down pretty well. Here are my pros, cons, and photos:

Note on Renovations: At least, some floors of the South Tower are still being renovated (based on the view looking up into the windows), and I'm not sure if there are still some unrenovated floors. According to the club staff, the whole North Tower is renovated now.

Pros:

• Despite being fully sold out online, I was informed at check-in that I was upgraded to an Executive Suite with a bay view before I could ask or inquire
• Executive Suite was attractively renovated with lots of furniture and great views towards the bay, city, and North Tower (note that these suites are the only rooms in the South Tower with balconies)
• Bed was quite comfortable with plush pillows and a plush mattress - covers weren't the thickest, but it's San Diego and the soft linens kept me comfortable
• Shower (appeared to be the only original part of the room) had nice pressure
• Internet TV OS
• Brought up a welcome gift of waters, M&Ms, and crackers
• Was able to get a late checkout of 1 PM (obviously a convention hotel) and a lounge access keycard to finish my meetings that afternoon in the M Club after checkout
• Service attitudes were quite friendly - asking about my travels, etc
• M Club was actually quite nice - tasty evening service options (spicy chicken wings, delicious dulce de leche cheesecake), and pretty good breakfast (absolutely wonderful cinnamon rolls + scrambled eggs and bacon)
• M Club service was also quite friendly - one of the evening attendants came up to ask me about my travels, how I liked my room, where home was, etc.
• Destination fee includes $15 F&B nightly credit - relatively tasty breakfast sandwich at the Exchange Market I had as an early lunch

Cons:

• Really small bar of hand soap - perhaps, this is an environmental choice, which would make sense to reduce waste?
• Towels should be updated - one out of three was pretty small (the one that wasn't Marriott-branded)
• Noise isolation both inside (water pipes in surrounding rooms) and outside (through balcony doors) could have been improved - though didn't bother my sleep

Overall, I felt like this was a great choice, and the M Club definitely seemed above average for the US.
