It's not that much of a hassle for us as our kids sleep on that end. My two boys sleep in the bunk and my daughter sleeps on the dinette bed. She's around 4' tall, so there's plenty of room to enter and exit the bunk without having to step over. During the day, we put the table in the shower (it fits perfectly in there) and that gives more sitting/walking room. We pull the curtains and close the bunk off so the kids don't have to put away their stuffed animals!
The slide out it what makes this camper work. We looked at the X17Z when shopping and it was just too tight without the slide out.
