Best for families and large groups who want direct Mission Bay access, multiple pools, on-site watersports and lots of meeting/event space.

Best for travelers who prefer a Shelter Island marina setting, boutique scale and easy access to nearby Harbor and Shelter Islands attractions.
When San Diego Mission Bay Resort wins: choose Mission Bay Resort if you need a family-oriented resort with many rooms and suites (357 total), multiple dining outlets, kids’ programming, tennis and a wider range of onsite activities and event space.
When Kona Kai Resort & Spa wins: choose Kona Kai for a quieter Shelter Island waterfront experience, marina access and a compact resort layout with spa services and watersport rentals — it’s a good alternative if you prefer a marina/habor setting to the busier Mission Bay strip.
Bottom line: both are waterfront Noble House properties in San Diego with spas and outdoor pools; pick Mission Bay Resort for scale, family amenities and event capacity, and Kona Kai if you want a marina-side stay on Shelter Island with a more intimate feel.
