I stayed in the Yosemite Suite during our last stay in September. We were comp upgraded. Still don't know why though.
The suite is very plush. It's like a small apartment. There is a nice size living room with a 36 inch Sony TV and stereo system plus a couch and chairs. The couch is also a pullout bed.
Then there is a small kitchen with a fridge and microwave. Wine glasses hang from above the sink.
The dining room is nice. There is a small table with chairs. Nothing special but the chandelier looks JUST LIKE the ones hanging in the main lobby but smaller. Definitely a showpiece of the suite.
From all of these rooms there are floor to ceiling windows which can provide you with the view of a lifetime. (Second ONLY to the view from Flag Family) Drapes can be closed for privacy.
The bedroom contains a NICE King size bed. The pillows were a little too soft for me and the bed was a little too hard for me.

There is also another 27 inch TV in the room.
There are of course two separate bathrooms. One half bath at the entrance in the foyer and the master bath which is HUGE and has a Jacuzzi tub!! Lots of room in this bathroom and let me tell ya, after a long day at the parks, the tub was a welcomed treat!
One of the nicest things about the suite was the view from the wrap around balcony. It is REALLY BIG. What a view. Unobstructed view of the lake and main pool area as well as the waterfall. Great for the Electric Water Pageant. There is also a table with chairs to sit down and enjoy breakfast and coffee outside in the morning. Lots of bugs at night. There is a panoramic picture I took and stitched together out of 9 pictures at my webshots picture gallery. Really nice view! Check it out here:
