When Aloha Stadium hosted the Pro Bowl in January 2016, problems on the road and at the gates marred the event, with thousands of fans stuck outside at kickoff and some even turning around and going home, frustrated that it was taking hours just to get into the parking lot.

Bruno Mars’ concert Nov. 10 will be the biggest event at the venue since, with 36,000 fans expected, and one of the challenges will be seeing that everything goes smoothly. Among the issues is the lack of parking at the facility — only about 7,000 stalls.

Ryan Andrews, deputy manager of the stadium, said Thursday that use of alternate sites is “already being discussed.”

For University of Hawaii football games, lots at Radford High School (within walking distance) and Leeward Community College (shuttle) add thousands of parking spots, and both are options, Andrews said. Parking at the stadium will cost $16 per vehicle.

Andrews also spoke about the possibility of a second show being added for the pop star, who was born in Hawaii and graduated from Roosevelt High School, saying that a decision on that would not come until the end of the first day of ticket sales, June 9. At the Stadium Authority meeting earlier Thursday, stadium Manager Scott Chan said there was a good probability of a second concert.

Tickets for any additional show would go on sale on a separate day, Andrews said, and rules currently in place for the first show — kamaaina presale, limit of four — would not necessarily apply. Andrews also said that if a show is added, it would not be scheduled before the first show — as has happened recently with comedian Jo Koy and rockers Def Leppard.

Nov. 11 — which is a Sunday but is the night before a holiday — is the most likely date for a second show, if one is scheduled, and even if two shows sell out quickly, Andrews said a third show would be “a long shot.”
