I have been to 50s PT about 10 times. Love it. For our last trip, my husband insisted on trying all new places. I booked Sci-Fi. Other than the unbelievably calorific yummy dessert, there is nothing I would go back for. I'm glad I experienced it, but don't need to go again. Sitting in the dark, eating a turkey sandwich, watching Tom and Jerry cartoons just isn't for me! In addition, I sat in the backseat by myself

Husband and daughter sat in front. I will definitely book 50's for our next trip.
Moral of the story...you wont be disappointed picking 50's over Sc-Fi IMO....
