I know some restaurants don't require reservations but some suggest that you do. We have picked out two or three restaurants around City Walk and some in the parks. We will be visiting May 20-23. Is it necessary for us to make reservations now for restaurants like Cowfish, Mythos, and some other restaurants around City Walk? We plan to eat at the NBC Sports Grill but I don't think reservations are needed there. We will be staying at Hard Rock Hotel and we may have a meal at the Kitchen. We are just trying to make our plans now and any advice would be greatly appreciated.
