The phones at the Four Points by Sheraton York hotel have been ringing off the hook.
"We are getting very close to getting sold out," sales consultant Lizz Todd said. "For the next few weekends, all we have open are kings rooms."
York may be about 30 miles from Gettysburg, but with a massive attendance expected, Gettysburg is running out of room.
"Hotels in Gettysburg are full at this point from what I understand, so that will overflow into York County," Todd said.
York businesses are also preparing for a colorful weekend.
"We are going to have theme cupcakes. We always do 4th of July cupcakes and have flags in them and do the red white and blue, so we will have that product. As for more product, yes, generally going into the weekend, we do, and if we know we have big events then we plan accordingly," said Sarah Koveleski, co-owner of Just Cupcakes.
Making their home in downtown York, Just Cupcakes is not taking the 150th Anniversary lightly. Koveleski said this is an opportunity to show tourists what they're made of.
"For downtown York, what's great about it is many of these people may have not been down here in years and a lot has changed, and I think we have a lot to be proud of right now," Koveleski said.
While many are passing through on their way to Gettysburg, York businesses will be more than happy to help them spend their money.
