The Dodgers and Giants face off this weekend in Los Angeles in what is setting up to be one of the best regular season series between the long-time rivals in recent memory.

They’ll enter Friday’s three-game series as two of the National League’s three 40-win teams and possibly tied for the NL West’s top spot, despite a more than $150 million payroll gap between free-spending LA and San Francisco.

Friday will feature Giants ace Logan Webb and Dodgers ace Yoshinobu Yamamoto in a heavyweight pitching matchup, and a possible series-clincher Sunday will come on Father’s Day of all days.

For any Giants fans making the trip to LA (maybe even with dad), there’s a better than good chance they’ll have booked a hotel (probably weeks ago) in nearby Downtown Los Angeles, where 4,000 National Guard troops have been deployed in response to protests of sweeping immigration raids enacted by America’s Immigration and Customs Enforcement agency. Seven hundred Marines were also activated earlier this week. 

The reason for their deployment there specifically is because the Metropolitan Detention Center, a federal prison where immigrants were held and protests erupted, is in Downtown LA. That neighborhood is now under an 8 p.m. to 6 a.m. nightly curfew, imposed for the foreseeable future by Mayor Karen Bass, that would possibly put visiting Giants fans in violation and up against arrest when returning from 7:10 p.m. games Friday and Saturday and maybe even Sunday’s 4:10 p.m. affair. Exceptions to the curfew are only permitted for those living and working in Downtown LA, credentialed members of the media, law enforcement and emergency personnel.

This exact scenario played out for an SFGATE colleague this week headed to Los Angeles for Sunday’s Giants-Dodgers Father’s Day game. He called to cancel a nonrefundable reservation at Courtyard Los Angeles LA Live and request a refund after reading about the newly instated curfew. The hotel had not shared any information with him about the ongoing military presence but happily obliged with a full refund, and the colleague booked a hotel room in another part of LA.

In making calls to several Downtown LA hotels, it appears that increased cancellations are the harsh reality for many of the properties, which are already suffering due to a hurting tourism industry in LA this year. According to two hotel managers who spoke to SFGATE on the condition of anonymity (granted in accordance with Hearst’s ethics policy), the hotels aren’t proactively informing guests about what’s happening in the neighborhood.

This confluence of events doesn’t bode well for San Franciscans who are making the trip to see one of the greatest rivalries in professional baseball and are possibly unaware of the curfew or its confines. As it currently stands, the curfew zone covers 1 square mile of Downtown LA (for reference: The city of Los Angeles encompasses about 500 square miles), which is a popular hotel and restaurant destination for visitors, especially before and after Dodgers games.

“We’ve seen significant cancellations,” a manager at the Downtown L.A. Proper told SFGATE. “I can’t share an exact number, but we’ve definitely seen an impact.”

When asked if the hotel was contacting guests about the curfew, she said, “We have information about it on our website.” That information can be found via a vague link at the top of the hotel’s website that leads to a page about the curfew and check-in protocols during curfew hours, though that link is only one item on a rotating carousel with marketing announcements about Father’s Day gift cards and travel awards.

The Delphi Hotel on Flower Street is also seeing decreased bookings.

“Everywhere around here, people are canceling,” a manager told SFGATE. “It’s similar to the Palisades Fire. We weren’t directly affected by it, but people don’t know how far things in Los Angeles are.”

She noted that the hotel also wasn’t proactively reaching out to guests but said, “We do tell people when they call that we’re open, business as usual.”

That is, if you consider military occupation and a nightly curfew outside of your front door “business as usual.”
