Worst restaurant breakfast service I've experienced in all my stays at Hilton properties. Was seated right away, (not the problem) the 10 min wait and no waitress stopping by for a drink order, food order or anything for that matter. Everyone else there had already been waited on and eating. She walked past other tables giving refills and didn't even bother looking my direction so I could wave her down. This is the service you give a Diamond member. I'd hate to see how you treat just the average guest.

Victoria is the best front desk agent always there to help my mother. No complaints ? also the housekeeper Beverly was nice and kept everything tidy.

Very disappointing experience. I got locked out of the hotel at 6:00 AM, and Cate at the front desk refused to let me back in. There was no effort to help or show any understanding of the situation. I was never notified for reason of turning my key off halfway through a month long stay. Poor customer service, especially at such an early hour when guests need assistance. I would not recommend staying here based on this experience.

A wonderful, clean hotel with an amazing staff! We spent a week here over the holidays into the new year and felt very well taken care of. The staff was very personable My only note for future guests is to check the bar hours if that's something you enjoy, as it was closed for most of our stay due to low occupancy. We did manage to catch it open once, and the service was excellent. Great food options near the hotel! We'd definitely stay again for the hospitality and cleanliness!

Doubletree, a very convenient location in Thornton. The staff was excellent, accommodating and very friendly. Lovely lobby, bar and restaurant. I stayed at Christmas time 2025 in the hotel had great decor, may be away from home at Christmas cozy. Anthony, manager at the front desk Was very helpful Christmas morning, grateful for that!

I stayed at the DoubleTree by Hilton Thornton for four nights and unfortunately experienced multiple issues that fell well below Hilton brand standards. During the majority of my stay, the wall thermostat in my room did not function. In addition, there are no exhaust fans in the hotel bathrooms. Combined, this caused the room to be extremely stuffy and humid, which significantly impacted our comfort and made the first three nights miserable. The issue was only addressed on my final night. The bar offerings were also extremely limited. There was very little alcohol available, including the absence of common selections such as Michelob Ultra and a very minimal wine selection. It raises the question of how a hotel can operate a bar when it is so poorly stocked. Another inconvenience was that a side entrance was not functioning, which was especially inconvenient for guests traveling with pets. I was also surprised to learn that complimentary tea is no longer offered. Free tea is a standard amenity across Hilton properties and part of what guests expect from the brand. As someone who travels frequently and stays in hotels regularly, this is the lowest-standard Hilton property I have personally experienced. I do want to emphasize that the front desk and housekeeping staff were extremely accommodating, professional, and kind throughout my stay. Nearly every staff member I interacted with went above and beyond to be helpful, despite the limitations of the property itself. Overall, this stay did not align with Hilton brand expectations, and I would strongly encourage management and Hilton leadership to review this property’s compliance with brand standards before recommending it to future guests.

We were on our annual trip from South Florida to Colorado. We visited Ester Park, the Rocky Mountain National Park, and attended the CU vs ASU game. Location was great for the price! Service was just as great as the location. All were friendly but Antony was exceptional!

Beautiful hotel. Good location close to the airport within 30 minutes. Rooms were very nice. Staff was great. I end up needing an extra longer check out due to is waiting for a ride to the airport and they were very accommodating. Loved they were next to a Starbucks walk out their door there it was.
