Celebrate nearly 400 years of history, romance, and intrigue in New Mexico at the Hilton Santa Fe Historic Plaza hotel - a grand destination honoring the city's past. Set amid a fascinating blend of Native American, Hispanic, and Anglo cultures, this classic-favorite choice of Santa Fe hotels preserves many of the architectural elements of the 350-year-old Ortiz Hacienda, home of one of the city's first families. Discover traces of this historic structure - including some of the original adobe walls - which combine perfectly with modern conveniences. The recent $1.5 million renovation of this beloved Hilton Santa Fe, New Mexico downtown hotel has restored the ambiance that existed over 375 years ago, when the Ortiz Hacienda occupied the entire city block. The spacious rooms, first-class service, and award-winning cuisine at our downtown Hilton Santa Fe hotel reflect a time-honored tradition of Southwestern culture and New Mexico hospitality.

A lovely New Mexico courtyard oasis with poolside fireplace and hot tub await each guest visiting this historic downtown Hilton Santa Fe Plaza hotel. Our 157 guest rooms are decorated in deep palettes inspired by New Mexico sunsets, hillside plant-life, and morning sky tones. Bask in the comfort of our downtown Hilton Santa Fe hotel, with trademark ultra-comfortable beds, flat-screen TV's, ergonomic chairs, and a modern work desk. Stretch out in luxury casitas, elegantly appointed with handmade furniture and ethnic fabrics. Guests will also enjoy room service, wireless internet access, a fitness center, valet and concierge at our New Mexico Hilton hotel.

The Hilton of Santa Fe hotel is set on historic grounds, located just two blocks from the famous downtown Santa Fe Plaza. Explore the city's unique collection of winding avenues and one-way roads on foot. Browse nearly 100 different galleries, featuring paintings, sculptures, and Native American crafts. Savor eclectic New Mexico style restaurants - each unique in flavor and ambience, humming with the rhythms of Spanish guitar, flamenco, blues and jazz. Just 16 miles from the ski basin, minutes from legendary golf courses, and steps away from the thriving culture of the downtown area, this timeless downtown Hilton Santa Fe hotel is central to everything you want to do in northern New Mexico.

Did you know?
Your support in staying at the Hilton Santa Fe Historic Plaza helps keep the conference costs down, which directly affects your registration fees. SIAM guarantees the hotel that we will fill a certain number of “room nights” (rooms per night) during the conference.  SIAM incurs penalties if too many attendees opt to stay in other hotels in the area or neglect to indicate to the hotel that they are with the SIAM conference. At this time, conference costs do not include meeting room rental. If SIAM fails to fill the contracted room block, SIAM is then charged the cost for the meeting rooms on a daily basis, along with a hefty penalty. Future registration fees could increase to cover these additional risks.


SIAM is holding a block of rooms at the Hilton Santa Fe Historic Plaza. These rooms are being held on a first-come, first-served basis at the following discounted rates. Please be aware the room block fills quickly, so we suggest you make your hotel and travel plans early.

The group rate is guaranteed until the cutoff date unless the block fills prior to that.  If there are rooms available after the cutoff date, they will be available at the best rate offered at that time.
