You can't move between hiding places with the hide skill. If you leave concelament and/or cover, you're no longer hiding (unless you have hide in plain sight or camoflage abilities).
So, if you're hiding behind a bush and want to move behind a wagon 10' away on a sunny day, you must leave hiding and then hide again. If you want to do this without being noticed, your opponent must be significantly distracted, usually requiring a bluff roll (perhaps throwing a rock or something to pull their attention away from your location).
Note that moving through concealed areas or areas blocked by parital or complete cover does not require you to leave hiding. If the wagon is next to the bushes, you can move from one to the next without leaving hiding.
If you move, you'll need to make a move silently role. The DM will decide on any appropriate modifiers.
