The DoubleTree website may be confusing, so below are a set of step/instructions on how to navigate the hotel’s website:
1. You will redirect to a Hilton.com page for the convention HQ hotel — the Rochester Doubletree (on Jefferson St. — there is another in Rochester).
https://www.hilton.com/en/attend-my-event/rocdtdt-ats-d3e90f9d-9826-4b42-a415-2e25e6a309d2
Scroll down past “Book your room” to second section title: Rooms & Rates
Under title are four lines of text in a blue tint box. THIS BOX IS THE LINK TO CLICK FOR BOOKING A ROOM. It says:
“Rooms at your event’s exclusive rate are filling up quickly. Visit the booking page and adjust the calendar to see which nights are available for your stay.”
>>> Inside “blue tint” box, click on the phrase “Visit the booking page”
2. You will redirect to the DoubleTree convention-rate booking page:
If you get a Hilton error message such as “page not found,” just start over and try again. It usually works on first or second try.
From here you MUST set the number of nights you want to stay — 5 for full convention, 6 for pre-glow and convention and 7 or more for everything.
Click on box with “1 night” and change it to your stay length. (5,6,7). Click the plus sign to increase the 1 to 5 – or whatever.
If more than 1 room or 1 guest, click the “1 room/1 guest” button to change the number of guests or add a second room.
You probably cannot go back to fix this later. If you forget to set correct nights or number of guests you are recommended to start over.
3. Very important: click “UPDATE” on the booking page (or else your nights will remain at “1”.
4. Scroll down to calendar. June 30 is the first night available. Most of you want to push the calendar to July — click JUL 2026 bar above the calendar. Select (click) your arrival (“check-in”) date. For example: Click on Mon July 6 for the first night of the convention. Observe the ATOS rate of $149 is displayed on each available date. July 6 is the “last” date to display as “available” because it is the START date of your 6-night stay. Your stay would be July 6 and the following five nights (through July 12), Hilton is not showing the entire stay — only the start date. (Confusing)
Scroll down past repeated hotel info to find actual rooms.
5. Click to choose room type. “1 KING with sofa bed” or “2 QUEEN Beds”.
That selection will take you to a page “Payment and Guest Details” to complete the reservation.
The printable registration form is available here.
The “Early Bird” registration period for the 2026 ATOS Convention has been extended to February 15, 2026. “Early” registration prices will begin on February 16, 2026.
