Top Alton Hotel Reviews

Drury Plaza Hotel St. Louis at the Arch

10/10 Excellent

"The room was excellent. The beds were very comfortable. All the staff were so friendly and helpful above and beyond of what I'm used to! The complimentary drinks and snacks we're so nice that we didn't have to buy dinner!"

Drury Plaza Hotel St. Louis Union Station

10/10 Excellent

"While I have never stayed in a bad Drury, this one has to be the best one yet! The location is great!! Walking distance to much of the great things we wanted to see in St. Louis. The hotel is very clean. The staff is very friendly. The architecture is beautiful!! The bed was very comfortable and the room actually stayed at the cool temperature we set it to, making it a very comfortable nights sleep! We will definitely be back!!"

Marriott St. Louis Grand

8/10 Good

"Room was clean and updated but needed an exhaust fan in the bathroom. Paint was peeling in some areas from the moisture. AC was very loud when it turned on and off and woke me up throughout the night. Within walking distance of Busch Stadium. Staff was there when the Cardinals game let out to help load elevators quickly. Parking garage was a block away, but it wasn’t too much of a walk. Overall, it was a decent stay for catching a Cardinals game."
