I am still in the process of deciding where we will be eating during our 2/4-2/8 stay. I need to make PS for dinner, but do I also need to for lunches?
Some of the sit down restaurants can be quite crowded during the peak 11:30 to 1:30 lunch times and there can be lengthy waits without a PS. However, the time you are going I would not be too worried about it. Also, even for dinner, you will find it fairly easy to get ressies by just calling the day before or early morning of. Ones where you probably want to make more advanced ressies are character meals in the parks.
