There won't be any formal RSVPs since this is just immediate family, so if you are unable to make it, please let Nick or Nichole know before October.
Friedman Memorial Airport (SUN) in Hailey, ID is the closest airport. It is located about 5-minutes from the AirBnB and about 15-20 minutes from downtown Ketchum, where Sun Valley Resort is located. Recommended flight options are provided in the "Travel" section of this site.
Fall colors are suggested - brown, dark green, orange, mustard yellow. Additional information on the dress code will come via text from Nichole. Keep in mind that the weather will most likely be on the cooler side, so I'd recommend a long dress with straps or sleeves.
