Pack n Play bassinet

So we have the pack n play below. I was going to use the napper as her bassinet the first few weeks but decided it would be best to use the actual bassinet part for bedtime, and only the napper for supervised naps. However I don’t want to take that part out at night because I like the idea of being able to use the changing pad at night rather than our bed or take her to the changing table in her room during the night. If we put her on the side where the mobile is in the picture and leave the changing pad, do you think that will be ok? I would think it’s fine until she starts getting big enough to take up more than that half and starts rolling over but I want some opinions!
