LAS VEGAS (AP) — The agency responsible for promoting Las Vegas says preliminary numbers show that fewer people visited the destination in 2017.

The Las Vegas Convention and Visitors Authority says more than 42.2 million people traveled to the area. That's a 1.7 percent decrease compared to 2016.

The agency attributed the drop to the mass shooting on Oct. 1 and a temporary reduction in available rooms as several hotels underwent renovations.

While the overall number of visitors fell last year, convention attendance increased 5. 2 percent, setting a record. The agency says more than 6.6 million people participated in conventions, which included the triennial large Conexpo-Con/Agg international construction trade show.

Revenue per available room, a key measure for hotels and resorts, reached almost $115. That's up 2.1 percent compared to 2016.
