Hi! My husband and I are taking our son to Disney World for his 5th birthday in October. We haven't been there for about 6 years and used to go quite frequently in the 1990's when we lived in Orlando. Back then, I don't remember having to make reservations everywhere...I was wondering if you have to make reservations at the nicer restaurants in the parks--or do they still allow for walk ups? We didn't want to be tied down to a specific restaurant on a certain day, not knowing how our days will go. We are not going to be on the Dining plan. Any suggestions are greatly appreciated! Thank you!
