City of Allen officials and Dallas-Fort Worth notables, developers, business people and North Texas influencers alike gathered for the topping-off celebration of the first-ever Texas location of Delta Hotels by Marriott Dallas Allen & Watters Creek Convention Center — and what will be the first Delta new build by Marriott in the United States upon its completion. Delta Hotels by Marriott Dallas Allen & Watters Creek Convention Center with 90,000 square feet of flexible and state-of-the-art meeting space will open in January of 2019. This location will be the brand standard for the Delta Hotels by Marriott brand going forward.
