Perhaps you can take another person in your life who you feel would be a great travel partner to Disney and lets say pay for the room portion and if you can afford it their airfare, or tickets, or all. This way you can have a great time with someone who also likes the parks. I've done this plenty of times in the past. You only live once. If you budget and forgo things during the year that you would normally buy for yourself. For example getting your nails done, or not buying a new outfit that you really want, coupons for food etc. You could start an extra Disney Account. There's so many ways to save up and justify a vacation that you enjoy. There is a lot on the budget board about credit card perks too.
Go, you deserve it!
