Hello Brian,
Thanks for stopping by planDisney with your question. It looks like your trip is coming up really quickly, unless your plans changed. In any case, making park reservations is a fairly easy process.
Before purchasing park passes and booking a vacation, I recommend checking the
Theme Park Reservation Availability Calendar. Unless you are traveling during an extremely busy time, like around Christmas or Easter weekend, you will probably find that all parks are available. The calendar is color coded: green means ALL parks are available, yellow means some parks are available, and grey indicates no parks are available. If you see yellow on a specific date, simply click the date to see which parks are available.
Once you've done that, you can start making your plans by
booking your hotel and purchasing tickets. As soon as you have purchased your tickets, you can start making your theme park reservations for the length of your trip. Although, if your trip is less than 60 days out, you may want to make dining reservations or reserve any special tours or activities first (like building a custom lightsaber at
Savi's Workshop), then select parks based around those plans. Of course, if your plans change, you can always cancel an existing park reservation and switch to a new park.
Hope this helps. Have a magical vacation!
Diane
