I have great news for you! Your daughter doesn't need a ticket since she is under the age of three; how awesome is that!
However, just to make sure I am reading your question correctly, you may be wondering about what ticket to get for yourself as well. If I were you, I'd get a 2 Day Magic Your Way Ticket since it looks like you're planning on visiting Walt Disney World for 2 days.
The big question then is should you add the
Park Hopper Option, which will allow you to visit any of the 4 parks. This can be a nice way to get to experience a sampling of each of the parks. However, you may find that you'll be very happy spending both of the days at just one park like the Magic Kingdom or visiting two parks over the two days. This is truly a question based on what you think you and your daughter will enjoy most. If it helps, you may want to look at the
Magical Beginnings Guide to see what attractions are geared for the younger guests (fyi, Toontown is no longer an option).
I hope this helps to give you a better idea of what ticket to purchase; please let us know if we can help again.
