I am returning my defective Roku Streaming Stick Model 3811X - to Roku Support - however since I will not have this device for a few days would I be able to use on my laptop or iPad -my subscription to ACORN?
If you're paying Acorn directly, I would think so. If you're paying through Roku then you may be able to access through "The Roku Channel" via their website or the Roku app.
