We purchased in 2004, after my first daughter was born.
Previous to purchasing, I had the opportunity to stay several times at the Dolphin and on the Beach Club Hotel during work conferences.
I remember walking by the Boardwalk thinking how great would be to stay there on vacation, walking right into epcot, but the epcot area hotel were expensive to my budget.
Now, I'm a DVC owner and not only I get to stay at the epcot resort in a 1 bd villa with kitchen, big bathroom, king size bed, and space for everyone to unwind and relax after the parks, but I do so at a very discounted rate, being able to pay my MF monthly without interests.
I also was able to trade my points last years for a stay at the
Disneyland Hotel in Paris, where you go from your hotel to the park in about... 1 minute walking, and the total cost of the whole trip was just about half what it would cost me if I had done it on cash.
There are minor disadvantages, like the need to plan well ahead of time my trips, when I was used to making last minute kind of plans using the florida resident room discounts. But that's ok, and I have to say I'm very happy with my purchase and I'm not planning in selling anytime soon. If anything, I may add-on on BLT in a couple of years.
