The Touring Plans map cited above is mostly useless since it is mainly designed to show non-
DVC rooms except for providing club level and value, and it is wrong even for the hotel rooms, i.e., if you go through a search on the map for any given type of room, it simply concludes that the particular type of room with savanna or standard view is located throughout the building. Disney Jambo hotel standard views bear no relation to DVC standard views. As a result, the Trip Advisor review mentioned above which is talking about a standard hotel room and not DVC, is also of no value in identifying DVC standard rooms.
The maps in the link provided in one of the posts by dekotix above,
https://www.easywdw.com/forums/showthread.php?35532-Room-Views-at-Animal-Kingdom-Villas-Jambo are the ones applicable to DVC Jambo and can be relied on regardless of anything else you might be finding online. The first map in that link shows where standards are located in blue -- the original standards were only the ones around the pool; the rest of the standards shown are savanna view rooms that were converted to standard view in 2012. It is possible to figure out the applicable standard room numbers by comparing that map showing the standards in blue to the map in the bottom of that post which shows all the DVC room numbers.
