From the moment you walk into their lobby at the hotel, you enter a place of calm and relaxation. We stayed in a room with the Water Tower view, and if you have that as the option, take it. It was a beautiful sight to see waking up every morning. This hotel like their other properties are in a class of their own.

  • Departing from or landing at other airports can sometimes save you money. Enter your preferred departure and arrival points. Next, select the 'Nearby airports' function below to see your options.

  • Bundle your hotels, flights and car rentals into one convenient package deal. Save your hard-earned cash for things you're really excited about, like discovering every corner of St. Charles.
