Have you tried Sci-Fi before? My dh and I went to WDW on our honeymoon and ate there. Yes, we were in the very back seat of a car with another family, but I did not feel the least bit out of place. I did not feel like I was having dinner with them, and did not feel that we were intruding on their dinner. Of course, if you have been there before and decided you didn't like the setup, that's a whole different story. Also, I have seen pictures that show a limited amount of small tables if you would be more comfortable with that kind of arrangement...
