Your layout isn't too dissimilar to our Hill Country 26RB and, with both slides closed, you have no access to anything aft of the kitchen island. So, no access to the bunkbeds.
If you want to have access, open the slide with the dinette. Otherwise, you won't be able to open the door wide enough to get access to the bunk area. Opening only the stove/fridge side won't do it.
