Stayed at POR-AB last Dec. and never had a long wait - maybe 10 minutes at the most. One time we did wait for the next bus as we were the last in line for MK and didn't want to stand up. The next bus came in about 20 minutes. I really don't think you'll have long waits. I like both resorts but I'm very partial to POR. Don't think you'll be disappointed at all with that choice.
Another good building choice at POR-AB is #16. We stayed in that one and found it to be a great location. There's a shortcut (through the bushes) just across the parking lot that ends up right at the bus stop. Of course, bldgs 14 - 18 are fairly close together so none are really far from the bus stop. Plus we found #16 to be quiet as it was not real close to the pool - but not far if you want to go there.
