The Disney Vacation Club is a great deal if you visit Disney every year. While I am not a member, my parents are. As a result, my family enjoys the privileges of tag-a-long-membership every couple of years. My parents are actually hoping that we will join them again this year in November so we’re trying to figure out if it’s possible for my husband (who has a few months of military school to attend).
Vacation Club allows you to stay at resorts that you would otherwise cringe at the prices. Plus you receive discounts on many purchases. I believe your ownership lasts for 40 or 50 years and can be transferred so it is a long lasting investment.
