Like the others, I agree that it's a matter of preference, but given the kids ages, I'd opt for Prime Time. First time we went, my DSs were 2 and 4. When asked what the 4 year old wanted, he said "doughnuts". We all laughed and reminded him we were there for lunch and of course, he cried and said that all he wanted were the doughnuts. About ten minutes later, the waiter walks up with a plate of various doughnut holes. The look on Spencer's face was great and happily he remembered his manners and thanked our waiter without being told. He had everyone in the restaurant seeking out other restaurant menus, vending machines, employee lunch rooms, etc. for doughnuts of any kind. Because of that cast member, we've eaten there on every trip (8th one in 3 years set for May 04)! Comfort food (especially the pot roast) was great and really what we wanted after lots of on the go park food. DSs were 3 & 5 when we tried Sci Fi. It was fun, food was good, but now that we have a DD of 6 mos., we'll skip it this trip since half the fun for the kids is sitting in the cars and it would be difficult to accomodate a third child, especially that young. Enjoy the magic!
