I am hoping they WILL be sister resorts. we fell in love with pop, and have been looking forward for a long time to them opening up the "other half"... we always walk across the "bridge to nowhere"

.
at the allstars, you can pool hop. no, one pool isn't much greater than another.. just a dif. view, dif. experience.
I thought they could have done a lot with the "legendary years " theme, but I know it would "go over the heads" of not only kids, but most of their parents!!
regardless, we looked forward to the finishing of the "enitre " pop resort, as it would expand the resort experience.
I will be very diappointed if they are not sister resorts. either way, I at least hope they keep the bridge open so pop guests can easily use the AOA food court (anyone, even offsite guests, can eat at any restaurant or food court at any disney resort)
hubby and I will definitely stay at AOA when the mermaid rooms are completed. ( In aug, we will have 2 rooms at pop with our soon, his wife, and our grandson. sometimes a week together for 2 families in a small suite is a little "too much" togetherness.)
if the bridge is open, and they do not allow pool hopping from pop to AOA, I agree with a PP.. I hope they don't allow it the "other way", then.

(why would anyone want to? the nemo pool might get crowded, and people always want to try a dif. pool, just for the heck of it. )
