Howdy Sarah!!
I love that you are thinking about D23! We joined a few months ago after one of our Walt Disney World Resort Vacations. We were in line behind a D23 Member and she went on and on and on about her experience with D23. She loved it and we knew we had to be a part of the magic!
D23 has Gold, Silver and Free Membership categories. Check out the website and make sure you take a look at the
discounts that are offered at Walt Disney World. While you may not find as many discounts in the parks as you might expect, you will be amazed at the number of discounts that are available overall. Whether you are interested in dining, shopping, travel or Broadway, you will find ample opportunities to immerse yourself in all things Disney!!
If you can't decide if it's right for you, I would suggest that you sign up for a free membership. As a member, you will be able to unlock the magic of the Official Disney Fan Club! Once you are a member, you can easily upgrade to either the Gold or Silver Membership level if you would like to.
If you become a D23 Member, be sure to check out the discounts right before you depart for your vacation to ensure that you don't miss out on anything new that might be offered.
Thanks so much for your question and please let me know if you need any further information as you plan your vacation. Have a magical day!
