Just a note that the Uffizi Gallery has ongoing renovations, rooms 2-7 and others are closed, and the art has been moved to other rooms, including the main level. If you use Rick's audio guide smartphone ap you may be confused, as the older works are not in sequence with the audio guide. Plan to go through both levels to see all the works mentioned in the audio guide.
Do they have an estimated date of renovation completion?
I didn't see it posted on the signs, but the Uffizi website news says spring of 2015, see http://www.uffizi.org/news/
I did the RS Audio Guide at Uffizi in mid-October. It was great as all of RS AG's. I understand what m.blessing says. As it was at the end of my trip, I was well practiced using the audio guide (at the beggining it was slower for me).
At the Uffizi, because of the renovation, I will use the RS free App, show the picture of the painting in the app to a security member or staff (there is one almost in every room) and they will guide me to the temporary room. Just keep in mind you will probably walk more (sometimes from one end to the other), but don't be affraid to ask. The Uffizi rocks! great museum! Good travels!
I used the Uffizi Audio. As "research" before going to the Uffizi. The audio. Is well organized. There were a lot of people in the Uffizi when we went and we had a child in tow. So, I listened to the app. ahead of time and just enjoyed a long, slow stroll through the Uffizi without it. I think this approach worked better for me and my family. The Uffizi is an amazing gallery. It 's really more than one can consume at one time anyway - just like our national Smithsonian. It would be great to live closer, go more frequently, and enjoy the collection in smaller doses.
