Holiday Inn Express Hotel & Suites Great Falls by IHG
The bathtub wouldnt drain for the first day of our stay, which is why i havent put a full 5 stars. However, every single staff member i interacted with was fantastic and hilarious to converse with. Would definitely visit again for the waterslide.

Always an amazing visit! I didn’t get to see sue but she’s a blessing to your hotel! The desk clerks are always so welcoming! The breakfast is good but I feel the cook should refill the food as it is almost out sucks to have to wait for 10 mins.
