Spark by Hilton will use the Think Simplicity’s communication platform at its Germantown Washington, D.C. North location. The Germantown property will be the second Spark by Hilton to debut in less than a year after Hilton announced the new hotel brand. It is the first in the Washington Region and the next in what Hilton has announced as a pipeline of more than 400 expansion opportunities in various stages of development around the country.
