Hi Jennifer! I am so glad I could help answer your earlier question.
When you purchase tickets, you do not have to specify which day you will be visiting each park. I do, however, suggest coming up with some sort of game plan before your 180 day dining reservation window opens up if you don't choose the Park Hopper option. With a standard base ticket, you are only allowed entry to one park a day. Of course, you are allowed to come and go, but it must be within the same park. If you opt to pay for the Park Hopper tickets, you have access to multiple parks a day. If you are going with the standard base ticket, you will want to be aware of what park you are visiting so you can make your dining reservations accordingly. I always check the
Walt Disney World calendar, during my travel dates, to see which park is offering Extra Magic Hours. We typically visit the park that has the Extra Magic Hours in the morning because the park is less crowded and we are able to walk on several of our favorite attractions.
Please feel free to ask more questions while you are planning your vacation. We are always here to help! Have a great day.
