Hi Patty H, Welcome to TA!
Yes, it is possible to visit Cedar Point from Cleveland and return the same day. Depending on where in Cleveland, it is an easy hour and a half drive west on I-90 / SR-2, and US-6. https://goo.gl/maps/QnheXvqt9J72
If you are visiting on a Saturday during HalloWeekends, I would suggest Fast Lane Pass as HalloWeekends tend to be the very busy.
Go to Cedar Point on a Sunday and you won't need to waste your time or money on the Fast Lane. Also get tickets either on line at cedarpoint.com or at Meijer in Sandusky. Don't go on Saturday at all costs.
