Hi, Kimberly! The Disney Dining Plan can be added to your reservation if you are also purchasing theme park tickets (dining must be part of a "package" not just "room only.") In the past, I have already had my park tickets so I simply add on a one day ticket for each person in my traveling party so we can add on the Dining Plan then use my current tickets for the remainder of my vacation.
I do not know your travel dates, but you might want to click on these
SPECIAL OFFERS. You may find that by adding on 2 tickets for each member of your party, you will qualify for Free Dining during your stay! Make sure to read travel dates and terms and conditions.
To see if you qualify for the Special Promotion, or to upgrade your current reservation to the Disney Dining Plan, call a reservationist at (407)W-DISNEY with your reservation number to see if they can work some Disney "magic" to make your vacation perfect for your family! Make sure to do this before your vacation, as the Dining Plan must be added at least 3 days prior to your vacation.
Have a great stay at the Beach Club and have fun at that awesome pool!
