I don't know if you are driving or flying, but there are kennels at Disney World if you want them to go along. The problem there is you would need to go walk them, and since you are only there eight days, I really think it would be more of a hassle than it's worth. Our dogs have been with us to WDW many times, but they get to stay in the camper at Ft Wilderness. Just an option if you WANT to take them.
With the number and ages of your dogs, they wouldn't get the same "full house" w/free reign to the doggie door treatment that most of my boarders get if they came to my home because I have a 13 year old dog and a 16 year old cat that need some "down time" from the chaos, lol, or I would offer to take them. Since I'm fortunate enough that I never need to board mine, I'll let other people give you referrals - I just wanted to let you know about the kennels at WDW.
Have a wonderful time, and if you have any specific WDW questions, feel free to e-mail me (we go often)!
