Contact SPG by phone and ask if a room booked with points includes daily housekeeping or not. Our Jetblue vacation package for our first stay at SVR did include daily maid service. Now that we're owners, we only get a mid-week tidy and towel refresh. Some rates do include housekeeping, others don't...but the SPG reps should be able to clarify that for you one way or the other.
The 2 bedroom villas range from about 1025 square feet (in Cascades) to 1500 square feet (townhouses in Courts). 2 bedroom villas in the other phases fall somewhere in between those upper and lower ranges. You can find the specific villa layouts here:

We find them very spacious....especially some of the upper villas that have the vaulted ceilings and skylights. We have had two adults and two older teens in those rooms and definitely didn't feel cramped. Just the opposite.....we had tons of room for all of us!
There are 7 pools, each with their own unique feature. The three "main" pools (open until 1 am) are located in Cascades, Fountains and Spas (the latter which is referred to as the Super Pool). The other secondary pools are in Lakes, Springs, Falls, and Courts. The Falls pool has a small slide, but its probably only going to be suitable for the 12 and under crowd. The Cascades pool has spray fountains and a waterfall. The Super Pool has in-water volleyball and a deeper middle section (with a sand volleyball court adjacent). The Fountains pool has in-water volleyball, a cascading water fountain, and a deep mid-section (with two raised, semi-private hot tubs adjacent, as well as two playgrounds. The Lakes pool is zero entry with a spray fountain.
Staying offsite, I would use my car every time. They offer shuttles to Disney (I'm not sure about Universal) but I didn't think the times were very convenient.
We think its a fabulous place for families.....so much so, that after our first stay we purchased two annual weeks there (resale, of course). There is a Publix very close by (right in the same area as the Premium Outlets on Vineland) and
Walmart is also super close. So far, we have stayed in Spas, Lakes and Fountains, and our overwhelming favourite (and where we own) is Fountains I....we love the layout of the villas, love the skylights in the uppers, and love the Fountains pool the best.
One thing to keep in mind is that certain sections and buildings are generally reserved for specific day of the week check-ins. Spas, for example, is reserved for those checking in on Fridays only. Which day of the week were you planning on arriving?
