Over the years, our experience has been almost exclusively 1 BRs. I hadn't noticed balcony coverage. Our favorite 1 BRs are 1137 and 1138.
As far as golf tee times, DH calls the different golf courses about a month in advance of our trip. There may be better ways to do it, but frankly I think he just likes to talk to the people at the golf courses, kind of like pretending he's there.
And there are bike racks for locking your bikes. Funny thing though-bring your own bike locks because when we were there last year, they gave us (as they always do) bike locks. However, everyone who rented a bike had the same 4 digit code to unlock their bike-1971-for the year WDW opened. Not very private though. I remember one day we were walking along when a family with bikes came by, and the lady said "Hey, I can't remember my bike lock combination." A man from down the way yelled over to her "It's 1971!" I kind of hope the resort gave up the idea of giving everyone that same code pretty quickly.
