Hotel prices in Ann Arbor are more than doubling this weekend as rivals, Michigan and Michigan State, prepare to face off on the gridiron Saturday night.

In one week, rates jumped from an average of $156 a night to $352 a night, according to an online price-comparison site, HotelsCombined, which looked at how the rates were affected by the huge influx of fans for the 7:30 p.m game.

Prices, the website's data showed, increased by a whopping 126% for Saturday, compared to a week ago, with the occupancy rate at 95% just before midnight Thursday and some of the few rooms left going for nearly $800 a night.

"The game is what is driving this," said HotelsCombined spokesman Ash Sobhe in Los Angeles. "It being late, and people are paying a little bit more not just for the convenience of it, but all creating an experience alongside it."

The game, at Michigan Stadium, is set to be broadcast on ABC. It is the first night game between the two teams at Michigan Stadium, and it is only the fourth home night game in Michigan's history.

Normally, Sobhe said, prices don't fluctuate from week to week by much more than by more than 5%, which means that there is tremendous demand for rooms this weekend in Ann Arbor. But, he added that it's a big game, and for some fans, the additional cost is "obviously worth it."
