San...this one has been talked over many many times recently, so you might not get many replies. That said, its a beautiful resort and I am sure your family will have a wonderful trip.
Its a short walk to DTD and the Congress Park rooms have a fantastic view of DTD at night. If you prefer to be near the center of things, ask for the Springs as it is close to the pool, restaurant, etc. There ARE bellmen there to assist you if you would like that upon check-in. The parking lot is set up more like OKW than a traditional hotel (due to the configuration of SSR - which is more condo than hotel style), but they are there to help if you want it. Every building has an elevator which helps with hauling bags, etc as well.
There is a very nice 5-10 minute path that leads to DTD. If you can't easily find it, ask. I hear the view from the quiet pool is fantastic, especially at night, so do take a stroll over. There is a boat service to OKW and DTD as well which my sons enjoyed a good bit when we stayed at OKW in April.
The Artist Pallet is not a traditional sit down restaurant (currently not one at SSR), but has an interesting selection of foods to try. No typicl burgers and fries, and parts of the menu change daily. There are lots of flat bread type pizzas and other items. Lots of people have reported that you can easily get variations to menu items simply by asking, so do ask!
Bus service sounds pretty good to me with the buses being almost empty a good bit of the time. One of our board members that has a wheelchair had a hard time recently, but hopefully that was a snaffu!
People that don't care for this resort tend to be those that prefer the full service hotel feel. That said, it appears that most people have enjoyed their stays here and I am sure your family will as well. No matter what your taste, its Disney so you know it will be top notch accomidations. The grounds are beautiful, the service has been reported to be fantastic (usually

we all have bad experiences occasionally) and the rooms are very nicely appointed. Have fun!!!
