I have also done two seperate condo's and many many disney resorts.
The extra room was nice, but I love coming back to the "Disney" feel all
the resorts have. I would say do the POP, they have a huge food court so, you would not have to cook and you have many pools to choose from, early and late entry, as they are changing the program and you would benifit at POP,then there are the buses and not to metion all the giant Icon's that would make you feel like you were always in Disney.
I just love living Disney when I go!!
good luck on your decision, I know it is hard. But when discount codes come
out for your time frame the difference in price may drop dramatically (meaning POP wouldnt be very much more.)
oh and it looks to be about 5-7 miles from DisneyWorld from the condo, but remeber there is usually traffic lights and all,
and add $8 a day to park at Disney unless you have an AP?
