GreenTree Inn San Diego Mission Bay is a 3-star hotel at 4540 Mission Bay Dr., San Diego, CA 92109, a four-story, 113-room motor inn that previously operated under the IHG Holiday Inn Express flag before converting to the GreenTree brand. The property includes a free hot breakfast buffet each morning — scrambled eggs, bacon, cheese omelets, sausage, pancakes, pastries, and Chobani yogurt options — which consistently earns top marks from guests as a standout value add. Less than a mile from the hotel, the Mission Bay Golf Course and Practice Center is the only night-lit golf course in San Diego, an 18-hole executive course on 46 acres that the hotel specifically highlights for guests. All rooms feature pillowtop mattresses, flat-screen TVs with premium satellite channels, a microwave, refrigerator, coffeemaker, and in-room safe, while the property offers an outdoor pool, sundeck, fitness center with weight-training machines, and a business center. Free self-parking and free WiFi are included; the nearest trolley stop on Balboa Ave. is a 10-minute walk, giving car-free guests an efficient link to downtown San Diego and Old Town. Families heading to SeaWorld San Diego, located 2.7 miles away, use the inn's free parking as a practical base for the park and the surrounding Mission Bay area. Check-in is at 4:00 PM and check-out at noon; a $50 refundable damage deposit is collected by credit card at arrival and returned within 14 days of check-out. The multilingual front desk staff operates 24 hours a day and has earned particular praise in recent guest reviews for helpfulness and professionalism.
