The San Diego Marriott Vacation Club property is currently called Declan Suites San Diego. It shares a downtown city block with the Joan and Irwin Jacobs Music Center (including the 2,231-seat Copley Symphony Hall), and the Symphony Towers office building (34-stories totaling 521,281 square feet). The hotel sits on top of a fortress-like parking structure with 650 spaces.
It remains to be seen how extensively Marriott Vacations Worldwide (VAC) transforms the hotel. Because it's part of an intensely developed city block, it cannot become a resort on spacious landscaped grounds with extensive outdoor areas.
Declan Suites currently has a relatively small heated indoor pool with skylights, and it seems very unlikely that a bigger pool is possible. You can find a photo of the pool and and other features of the hotel here:

Declan Suites boasts "over 6,000 square-feet of flexible San Diego Meeting Space with large pre-function space" on its 12th floor. Presumably, that space can be put to different use for Vacation Club guests.
Perhaps there's an opportunity to add an outdoor deck on the roof between the two towers or to peel back part of that roof. Given San Diego's wonderful year-round climate, it would be a shame if that does not happen.
The rooms are all 425-sq.ft. 2-room suites. Currently, they're really just traditional hotel rooms with a wall dividing the bed area from the sofa area. There are no balconies. These "villas" will be smaller than purpose-built Marriott Vacation Club villas, but I hope that VAC will skillfully squeeze in a mini-kitchen and more "home away from home" features.
By the way, VAC's acquisition of the hotel is complete. According to Marriott Vacations Worldwide Reports First Quarter 2015 Financial Results (April 30, 2015):
The company completed its acquisition of an operating hotel located in San Diego, California, for approximately $55 million. The company plans to begin converting the hotel to vacation ownership inventory later this year.
