DoubleTree by Hilton Hotel Portland

The hotel is one of the five largest in Portland, with 477 guest rooms as of 2020. The property also has restaurants, a covered parking garage and a conference center.^[3] The hotel has fifteen floors and multiple glass elevators.^[4] The outdoor pool, among few at Portland hotels, can accommodate approximately 20 to 30 people.^[5]

The hotel opened as the Sheraton-Portland Hotel on September 28, 1959,^[6][7] owned by the Lloyd Corporation and operated by Sheraton Hotels.^[8] It was the first new hotel in Portland since the opening of the New Heathman Hotel, in 1928.^[9] It was renamed the Sheraton Motor Inn in 1963.^[10]

In June 1980, the hotel was purchased from the Lloyd Corp. by the Thunderbird–Red Lion Inns chain,^[9] and became the Red Lion Inn/Lloyd Center on August 1 of that year,^[11] the latter part of the name referring to the Lloyd Center mall, located across Multnomah Street from the hotel. The nine-story hotel had 276 rooms at that time, but a major expansion – including the addition of a 15-story tower – was planned.^[9] When the expanded hotel reopened in 1982, it had 520 rooms and was the largest hotel in all of Oregon.^[2]

In 1989, with 476 rooms, the Red Lion Inn/Lloyd Center was still the second-largest hotel in the state, after the 503-room Portland Marriott Hotel in Downtown Portland.^[12] In September 1996, its owner, Red Lion Hotels, Inc., then based in Vancouver, Washington, entered into an agreement to be acquired by then-Phoenix-based Doubletree Corp.^[13] The merger closed on November 8, 1996,^[14] and the Lloyd Center hotel was renamed the Doubletree Hotel Portland.^[15] In October 1998, Doubletree announced plans to expand the hotel with a new 300-room tower to be constructed on the northeast corner of the property, in order to make the hotel a 'headquarters hotel' for the nearby Oregon Convention Center.^[16] The addition was never built. In late 2010 and 2011, all Doubletree hotels were rebranded as "DoubleTree by Hilton".^[17]

A woman was found dead in one of the hotel's stairwells in late 2014. A Washington man was accused of murder and arrested.^[18] The woman's family sued Hilton and the hotel's owners.^[19][20]

In 2019, a man filed a $10-million lawsuit against the hotel, claiming that he was racially profiled during his stay in 2018.^[21][22][23] The hotel issued an apology and fired two employees.^[24][25][26] The hotel's operator, Hilton Hotels & Resorts, said that the company has "zero tolerance for racism".^[27]
