I felt it was all so confusing there. The parking is horrendous. You get an email stating 45 a night for self park but it’s 65-this is directly from the hotel. I ordered my room through Orbitz. Don’t get insurance through Orbitz as the hotel charges insurance as well. Expect a hold fee for incidentals of 70 a night. The room was clean. But minor scuffs. I took photos to make sure a charge didn’t come back to me. Bus is the way to go as the city is overpriced on uber. Orbitz does not match the hotel price be aware. It would seem like my issue is with Orbitz but it’s the hotel with all the surprise fees. If you’re looking for a clean hotel this is it. If you’re looking for friendly staff this isn’t it. If you offer someone something like water then you should offer everyone, I work in property management and if I offered someone something and not the next it would be a problem. Just saying. The pool is small. And right next to the gym and on the 10th floor. We were on the 18th and it wasn’t bad but just ok. Would I stay again probably not. I am big on friendly staff. Park other places as you can find way cheaper. We stayed for 3 nights. 195 total. Photos attached are the day we left. I don’t play when it comes to picking up behind myself.

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.

  • To refine your results, click on 'Show options.' You can search based on airlines, seating class, and nonstop and refundable flights. You can also select whether you want to fly in the morning, afternoon or evening under 'Sort & Filter' to the left.

  • 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.
