Hi LeAndra,
Taking a Disney vacation can be expensive, even if you do it on a budget. That doesn't mean there aren't deals to be had. Disney runs some great promotional specials, like free dining, at different times during the year. If you belong to AAA you can also get some pretty good vacation packages.
First consider your resort options and when you want to travel. If you want to stay on property, Disney's Value Resorts are ideal. During slower seasons (September, February), resort rates are going to be much less expensive than during peak season (summer, Christmas, Spring Break).
Right now there is a
special for summer vacation travel for 6 night stays June 15 - August 14. If you travel during this time period, you can save up to 25% on your stay.
Mouse Savers is an online site that lists a lot of great ideas for saving money on a Disney vacation. Check out there site for tips on saving when purchasing park passes, food, etc.
Hope this helps. Have a magical vacation!
