Like many prior have said, when you stay at a Disney Resort, you can travel all over Disney property using Disney Transport.
If you're not looking for theme parks during your 2 day stay... check out some of the following fun ideas.
--Mini Golf at the Winter/Summerland mini golf course. (Located at Blizzard Beach) Transportation is provided to and from BB every 10-15 minutes until 8pm. There are two courses here, both are a lot of fun.
--Animal Kingdom Lodge... a beautiful resort to walk around and explore. Lots of animals to see, activities, and wonderful restaurants. To get from All Stars to AK Lodge, before 6pm, head over to DAK. After 6pm, try connecting at Studios or other theme parks.
--The Polynesian is also a beautiful resort to walk around, and explore. At the Polynesian (As well as the other MK resorts) you can rent sail boats, water mice, and other things. They also have a Luau to go to. In addition, you can see the MK Fireworks from thier beach.

To get to the Poly, take the Magic Kingdom bus, and the use the Resort Monorail.
--And of course, Downtown Disney. At DTD, you can go shopping at all those wonderful stores... party at Pleasure Island, or take in La Nouba at Cirque du Soleil... It's a bit pricey, but VERY much worth it. Absolutly AMAZING show. If you haven't seen it, try and go see it.
Of course theres tons of other things to do (including lounging by the pool), but I think you get the idea... Go for the All-Stars... relax, and have fun.
