Hilton Garden Inn St. Louis Shiloh/O'Fallon  

In O'Fallon, just off Highway 64 at exit 16 Green Mount Road. About 15 minutes from St. Louis and roughly 10 minutes from Scott Air Force Base, this hotel sits connected to the convention center and close to St. Clair Square Mall and nearby golf courses.

Perched in front of a six‑acre lake with fountains, the property offers 128 spacious rooms with microwaves, mini‑refrigerators, Keurig coffee makers and 32‑inch flat‑screen HDTVs with HBO. Select suites add whirlpool tubs and separate showers or a separate sitting room with a sleeper sofa for extra space and comfort.

Swim in the indoor heated pool or unwind in the spa tub. Work out in the 24‑hour fitness center—there's even a Peloton bike—or stroll the lakeside paths and drink in the fountain views.

Complimentary wired and wireless high‑speed internet and a 24‑hour business center keep meetings moving. Meeting rooms and a large on‑site conference center offer meeting packages and catering, plus express check‑out and free self parking.

An on‑site restaurant serves breakfast, lunch and dinner and features a bar with garden views. Cooked‑to‑order breakfasts are available daily for a fee, and limited‑hour room service lets you keep it easy in your room.
