We were there on an exchange Jan. 6-13, '12. The pool is designated in the 2nd building and the guy at the desk, who was also in the sales office, said they don't know when it will go up. Said the resort was about 65% sold. Also told me the summer owners choose to rent through their rental program instead of trade. (Sound like a sales' pitch?) I was hoping to find an owner who would want to do a direct exchange. There is one owner who placed a review in the Resort Database but didn't designate that he could be contacted.
Not having a pool was a bummer but even more than that was they didn't designate even a small space for any exercise equipment until the next building opens. They send you to a local gym which I found very inconvenient.
This past July we stayed at Bay Harbor on Marriott Reward's points. Found out it is also in the timeshare pool. We had our bikes with us. There is a 25+ mile pathway that runs right by the resort. It goes west into Charlevoix and east to Harbour Springs. We only went as far as Petosky. It's a strong uphill to Charlevoix and a good downhill to Harbour Springs, but then you would have to come all the way back uphill.
We went to Traverse City for some winter fun in the snow. Instead we had weather in the 40's. So we did a Plan B and went for eating roadtrips

to Leland, Old Mission and Petosky. Even drove as far as the Leg's Inn even though it wasn't open. Couldn't do that if the weather was bad. We did stop at the General Store in Good Hart which is always fun.
In Traverse City we enjoy eating at the Apache Trout and Grill. In Petosky the Twisted Olive Cafe was great! We also like to browse McLean and Eakin bookstore in Petosky.
When our son was small (27 years ago) we would take him to cabins in this same region of Sugar Beach. No amenities, no pool. One small t.v. One shower (I bathed him in the large kitchen sink). It had a small kitchen and door on small bedroom. We loved it. Now we're spoiled with our timeshares.
