Hotel
We've reserved a block of rooms at the Best Western in Fergus, Erin's neighbouring town. You can call the front desk and mention you're a guest of Emily's and Oleg's wedding for a preferred rate.
Travel Note
While hotel options are minimal around Erin, consider staying at an AirBNB in Erin, Fergus, Elora, Orangeville or Caledon. If you're not planning on driving back to your accommodations after the wedding, you can leave your vehicle at the venue for pickup before 11 am the next day for a stress-fee, fun time :)
