I would say that disney is still one of the best places to go for an overall vacation - but there is a heafty price tag associated with it. Disney does not typically offer discounts, especially to non-florida residents. You can try to reduce your costs by purchasing a multi-day ticket and/or staying at one of the value "All Star" resorts on disney property (you still get use of all of the disney transportation services).
Try to go off-season to avoid the heat and crowds. Use the fast-pass system when available.
