We have a Cedar Creek 36CKTS with 3 hydraulic slides. Although there is a single switch to open/close the slides, you can also select to open/leave closed one or more of the slides. I haven't personally done this, but it can't be difficult to access and operate or my husband would have complained about it. It has been no big deal when we have wanted to open a slide to access a closet or certain cabinets.
That said, having access to the refrigerator and bathroom without having to move a slide makes a pit stop to use the bathroom or grab a drink from the fridge a lot easier and quicker.
