Naveen is typically worth the wait. It is great to get them both together and unless things have changed if you wanted a separate picture with just one of them, they will do that. When we saw Tiana in October, no one seemed to really realize she was in Heritage House even though there was a sign by the door. We walked in and there was no one there but Tiana and the photographer. When we left, no one else had walked in to see her. We knew she was in Heritage House, but didn't realize where that was (after a bunch of WDW trips), and someone else had to point it out to us. You might try seeing her by herself earlier in the day when there is no line, and then try again to catch her with Naveen if the wait is not too bad.
