Previous posters are correct off site without car not a good idea. But remember if you have no AP it's 12.00 a day to park at the parks. How about on site at one of the value resorts? Downtown disney an option.
You can rent a condo or townhouse off site about as cheap as a hotel room. Even with just DH an I it's nice to have 2 bathrooms, washer an dryer, couch etc along with being able to cook if you wish. I'm gonna fry up sausage about 3 lbs when we arrive at our townhouse we will have that with eggs an biscuits, eggs an waffles etc during our 10 day stay.
With a washer an dryer not near as many clothes needs to be packed throw a load in washer at night right before going to bed 1st thing in the am put them in dryer an they be dry an ready to come out of dryer before you head out to parks or you can leave them sit till ya get back from park.
For my June stay off site traveling on a harley from Indiana I'm taking 4 outfits for disney with maybe spare pair of socks to change socks mid day I'll leave those on the harley go back out an change socks. I'm taking 2 pairs of shoes an a pair of
crocs. Plus I'll have 2 changes of riding clothes for the ride down an back so we really really need that washer an dryer.....
The 2nd bedroom won't go to waste with just DH an I cause I'll put all my stuff in there an use the 2nd bed an bath for getting ready in then DH an I not falling over each other when gettin ready.
