Best for families, groups and events who want marina/bay access, multiple pools and large meeting/wedding venues.

Best for travelers prioritizing a beach/bay vacation with on‑site water activities and a full-service spa in a Polynesian-themed setting.
When Sheraton San Diego Resort wins: choose the Sheraton if you need a property very close to downtown, the airport and convention centers, want extensive meeting and wedding facilities, or are traveling with kids and want multiple pools and family programming.
When Catamaran Resort and Spa wins: pick the Catamaran if you want a Mission Bay beachfront/bayfront resort with direct beach access, on-site water sports and a full-service spa in a relaxed, Polynesian-themed setting.
Bottom line: Sheraton centers on bayfront convenience, multiple pools and big-event capacity; Catamaran centers on beachfront leisure, water activities and an island-resort vibe. Your choice hinges on whether proximity to downtown/airport and event space (Sheraton) or direct beach/bay leisure and a dedicated spa (Catamaran) matters more.
