You can't change the Title for specific dates. Keywords will work for Google searches, but not necessarily Airbnb. I suggest changing your Title and maybe the first line of your description. 45mins from where they are doing the NFL draft isn't necessarily very close, but you know your market better than me 😊. Don't think you need to say "Red Barn" in your title - guests can see that from the photo and you're using up valuable space in your 50 character title. Only 32 characters show in the thumbnail photo in searches. The fact they you are on the river also implies the other benefits: fish, beach, boat, sunsets. You want your best, most unique amenities listed in the Title:
Current Title
Red Barn on the River-Fish, Beach, Boat, Sunsets
Suggested Title
On River! Lambeau Field 40mins! Beach/Boat/Views
The above Title first portion will show on the thumbnail photo (30 characters), which is what you want, but also highlights your River location. The rest of the Title (whole 50characters) will show if the guest clicks into the listing page.
Description
I would then put this in the first line of the Description:
"Only 40 minutes away from Lambeau Field! Perfect for the NFL Draft and Packer games."
Google Search
A few days after you make the changes, do a Google search for Lambeau Field, NFL Draft and Packers and see if your listing appears in results.
