San Diego Marriott Hotels ranked from my experience:- Hotel Republic
- Courtyard Downtown
- Coranado Island Marriott Resort
- US Grant
- Courtyard Gaslamp
- Springhill Suites Marriott Downtown/Bayfront
- Marriott Marquis Marina (my least favorite Marquis I've ever been in)
- The Westin San Diego
- The Westin San Diego Gaslamp
- Moxy San Diego (How they can sell those rooms for that price is criminal)
As you can see there is no shortage of Marriott hotels (I still have like 6 I haven't been to) and finding 7 day availability will be really hard with all the different conventions. Been coming out to San Diego pretty much every week for the last few months. I've had to jump around way way way more often then I would like to.
