That is correct. Unfortunately, hotels do sell out rather quickly for the weekend. You may have some luck finding some available rooms using this link...see more
Thank you for the link but as I said anything in newark and Wilmington is booked and you have to look in PA or even Maryland at least 30 miles and plus away from UDEL!
I booked an air bnb last year and this year as soon as they announced the dates. You might have better luck there.
It’s impossible to find a hotel nearby for Oct 7th - 8th … only availability I found was Hilton Kenett square in pa
