We're not reserving a block of rooms in any one hotel, but we can recommend a few:
The Strathallan Hotel - we love this place because it's on the street Rachel used to live on. It's in a great neighborhood for wandering around in on Saturday.
The Staybridge Suites - right across the river from the Interfaith Chapel at the University of Rochester, where the ceremony will be held.
Hampton Inn - closer to the reception site.
All of these options are comparably priced.
