Ameristar Casino Resort Spa: St. Charles's Riverfront Entertainment Destination

Perched on the bank of the Missouri River just off Interstate 70, the Ameristar Casino Resort Spa is one of the largest and most recognizable entertainment destinations in St. Charles County. Part casino, part resort hotel, part dining and nightlife district, and part spa retreat, it draws visitors from across the region for everything from a night at the tables to a weekend getaway. For a city with as much history as St. Charles, Ameristar is a reminder that the riverfront is still where people come to have a good time.

Whether you visit for the gaming floor, the restaurants, a concert, or simply a relaxing overnight stay, Ameristar packs a full resort experience into one riverfront address, and it does it at a scale few venues in the region can match.

A resort this size runs thousands of connected systems around the clock, from the gaming floor to the front desk. Nothing can go dark, ever. Local businesses feel a smaller version of that same pressure every day. While our headquarters are based in St. Peters, our team supports businesses throughout St. Charles and the greater St. Louis region. Proactive managed IT services are what keep the technology behind a nonstop operation running smoothly.

One of Missouri's Premier Casinos

Ameristar St. Charles grew out of Missouri's riverboat gaming era into one of the state's largest and most complete casino resorts. Its expansive gaming floor stretches across more than a hundred thousand square feet, filled with slot machines, table games, and a poker room, making it a destination for casual players and serious gamers alike. The scale alone sets it apart. Walking the floor, the sheer size of the operation is part of the spectacle.

But what distinguishes Ameristar from a standalone casino is everything built around the gaming. Over the years it has expanded into a full resort, adding a hotel tower, a spa, an events center, and a lineup of dining and nightlife options that give visitors plenty of reasons to stay beyond the casino floor. That evolution turned it from a place you visit for an evening into a place you can settle into for a whole weekend.

Its riverfront setting and easy access from I-70 make it a natural anchor for the St. Charles entertainment scene, and it consistently ranks among the region's top gaming and hospitality destinations.

Dining and Nightlife

Ameristar is as much a dining destination as a gaming one. The resort's Bottleworks streetscape and its restaurants offer a wide range of options, from a steakhouse and buffet to casual eateries, bars, and quick bites, so guests can find everything from a special-occasion dinner to a late-night snack without leaving the property. The variety means the resort serves both the casino crowd and locals who come simply for a meal or a night out.

Nightlife rounds out the experience, with bars and lounges that keep the energy going into the evening, plus live entertainment and events throughout the year. The combination of dining, drinks, gaming, and shows under one roof is what gives Ameristar its all-in-one appeal, and it is a big reason the resort stays busy well beyond typical dinner hours.

Every restaurant, bar, and retail outlet at a resort handles a constant stream of payments and guest data. Protecting all of it around the clock is a serious responsibility. The right technology setup keeps a busy, transaction-heavy business secure without slowing it down.

The Hotel and Spa

For those who want to make a night of it, the Ameristar hotel offers well-appointed rooms and suites just steps from the casino and dining. The convenience of staying on-site is a major draw for out-of-town visitors and for locals looking for a staycation, and it makes the resort a popular choice for celebrations, group getaways, and events.

The full-service spa adds a layer of relaxation that sets Ameristar apart from a typical casino. Guests can balance the energy of the gaming floor with massages, treatments, and quiet time, turning a visit into a genuine retreat. That mix of excitement and relaxation is central to the resort's identity and part of why it appeals to such a broad range of visitors.

A Hub for Events and Groups

Ameristar's event and conference space makes it a frequent host for gatherings of all kinds, from corporate meetings and banquets to concerts, holiday parties, and special celebrations. The ability to combine event space with on-site dining, lodging, and entertainment in one location is a strong selling point, and it keeps the resort's calendar full throughout the year.

That event business also connects Ameristar to the wider St. Charles hospitality scene. With The Family Arena, the St. Charles Convention Center, and Historic Main Street all nearby, the riverfront area functions as a genuine entertainment and event district, and Ameristar is one of its anchors. Visitors often combine a stay at the resort with a show, a game, or a stroll through the historic district.

Resorts, arenas, and convention spaces all scale their systems up for big events and back down afterward. Managing that flexibility well takes real planning and support. A responsive help desk keeps a busy team moving when questions and issues come up fast.

Nearby on the St. Charles Riverfront

One of Ameristar's advantages is its location at the center of the St. Charles riverfront. Historic Main Street, with its shops, restaurants, and founding-era landmarks, is just a short drive away. Frontier Park and the Katy Trail offer riverside walking and biking, and The Family Arena and St. Charles Convention Center are minutes away for concerts, sports, and expos.

That concentration of attractions means a visit to Ameristar can easily expand into a full St. Charles experience: a show at the arena, a stroll down Main Street, a meal on the river, and a comfortable stay at the resort. For out-of-town guests especially, the resort makes an ideal home base for exploring everything the area offers.

Tips for Visiting

A few things to know before you go:

  • Getting there: right off I-70, with ample parking including a garage and valet

  • Age and access: gaming areas are 21 and over; the restaurants, hotel, and spa welcome a broader range of guests

  • Busiest times: weekends and event nights, so book dinner, rooms, and spa appointments ahead

  • Quieter visits: weekdays are more relaxed

  • Explore nearby: the rest of the St. Charles riverfront and Main Street are minutes away

Ameristar delivers a seamless guest experience, day and night, because everything behind the scenes keeps running. Your business deserves that same reliability.
