Karen it's so wonderful to know that you are passing on your love of Walt Disney World to the next generation; it must be so magical for you to enjoy the Parks anew through the eyes of your darling little grandchildren.
Bringing your family to Walt Disney World Resort on a budget is an achievable goal. A good starting point would be to keep a check on the Disney website for
Special Offers, you might spot a really unbeatable deal that would be just right for you.
There are several fantastically themed
Value Resorts to choose from and just because they are less costly to stay in doesn't mean they aren't as magical.
Thinking about when you'd like to visit can keep you within budget too. A mid week stay is generally less costly than at the weekend and lower off peak seasonal prices make can a big difference to the overall price you pay.
How about purchasing
Disney Gift Cards as and when you can afford them? The gift cards can be put safely to one side and then used during your vacation to purchase meals, snacks, souvenirs and so on.
If I can be of any further help to you, please don't hesitate to come back and ask me another Walt Disney World Resort planning question.
Have a great Disney day.
