I travled to Sun Valley in August 2006. I booked late and could not stay at resort. However I found a one bedroom studio apartment at Elkhorn for a better price. Very clean, stocked with everything I needed to cook with. Nice view. Able to use pool and weight rooms. I am definitely planning to visit again and will choose this resort!
Two things that are negatives: no cell phone coverage and I do not have calling cards. So depending on what area of the resort you are at, get a card. Also there was construction and the lot was dark and unpaved to park in. However I am sure this is fixed. more
