Kaity Bucaro and Robbie Morris of Chicago's River North neighborhood had to cancel their wedding, which was scheduled to take place in Guadalajara on Friday.
After ABC7 Chicago reported about the couple's need for a an emergency venue, The Alston reached out.
"I said, you know, I'm going to see what I can do to help," said Nicholas Cuda, The Alston managing partner. "Marriage is unique thing, and for her and her fiancé to be going through this at this point in time, not being able to continue to the destination wedding wish they planned, for me it was heartbreaking."
"We spent yesterday and today trying to find a venue, someplace we can host this wedding. And that's on our to-do list today," Bucaro said.
"So we had 150 guests ready to board flights and get down to Mexico for the wedding. We've had really great feedback from our friends and family, saying 'wherever it is, we'll be there,'" Morris said.

Meanwhile, Ursula Cirkovic's son decided to keep his wedding plans in Cancun.
"[On] Sunday, we were like probably canceling and waiting for the airline to cancel, but everything was on time. All the planes were going," Cirkovic said.
She said some wedding guests have canceled last minute out of fear for their safety.
"My sister, she's just a little bit more afraid. So, it'll be maybe fewer guests," she said.
Leaders in Mexico say things are much calmer now.
People like Lorena Aranda say the recent unrest has not deterred her from traveling to Mexico.
"Yesterday we were still debating whether to go or not, but we have family that work for the military over there. And they're like here. We're good; we're calm. So, we're praying for the best," Lorena Aranda said.
"We are praying for the best. We checked out some resources, the government, the embassy. They said it's all clear. So, we plan for this vacation for a long time; so it is what it is," traveler Chris Cieplevicz said.
Jenny Buenrostro is in Puerta Vallarta for her birthday, and has no intention of cutting her celebration short.
Vacationers there said Sunday night was chaotic.
"There were so many vehicles on fire, with gas tanks exploding. And then there was gunfire all around us, and so it was kind of pandemonium," Yoni Pizer said.
Even though, Americans in Puerto Vallarta and Guadalajara are still being encouraged to shelter in place, some travelers feel safe heading into the region.
