Conference Hotels in Arizona

Phoenix and Scottsdale concentrate most of Arizona's large conference hotels, with properties like the JW Marriott Camelback Inn in Phoenix and the Fairmont Scottsdale Princess in Scottsdale offering extensive event capacity. Tucson also features sizable conference hotels, including the JW Marriott Starr Pass Resort and Spa with 49 event spaces and a largest space of about 20,000 square feet. These three metros account for the majority of the state's meeting and event inventory.

For a large conference or corporate event, aim to secure your room block at least six to nine months ahead, especially if you're targeting high-season months in Phoenix or Scottsdale. Properties with significant event capacity often fill their calendar early, so reaching out a year in advance gives you more options. Booking early also helps lock in pre-negotiated rates and gives attendees time to plan travel.

If your stay requires 9 or more guest rooms, Engine Groups handles the room-block booking; for 8 rooms or fewer, you book self-serve through the platform. For the meeting or event space itself, planners can find and request a venue through Engine Spaces, which gives you access to meeting and event venues across Arizona. That way Engine supports both sides of your event: the accommodations and sourcing the right space.

Look at each hotel's largest event space and the number of breakout rooms it offers, for example, the Fairmont Scottsdale Princess has a largest space of about 23,000 square feet and 43 event spaces, while the JW Marriott Camelback Inn in Phoenix offers a largest space of about 38,000 square feet and 30 event spaces. Also consider guest-room count (the Fairmont has 750 rooms, the Camelback Inn 453) and capacity for your general session, properties on this list accommodate anywhere from up to 1,950 people to up to 2,990 people. Factor in attendee access to the airport serving each city and what your group will do outside the sessions.

Engine offers consolidated invoicing, so you see all room charges on a single bill rather than chasing receipts from individual travelers. You also have multiple payment options and there's no membership fee to use the platform. That simplifies accounting and makes reconciliation straightforward for finance teams managing large bookings.
