With little chance for a last-minute booking in Yosemite Valley, we decided to stay in Fresno and make the drive to the National Park (about 2.5 hours) for a day trip. Based on TripAdvisor reviews, we chose the Homewood Suites by Hilton, Fresno, and were very pleased.
The property is well-kept, very clean and the front desk staff was wonderful. With my wife and two kids (age 14 and 9) along for the trip, the room was well-sized for our family and the kitchenette was a nice added touch. The master bed (a king) was comfortable, the sink and vanity well lit, and the shower was large with plenty of hot water flow.
As far as drawbacks... Our room (an "inside" room on the first floor) was quiet, but my wife was awakened more than once during the night by the air conditioner (a "window unit") cycling on and off. My kids also found the pull-out sofa bed very uncomfortable — maybe two queen beds would have been a better choice?
